Significant Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Note 1 – Significant Accounting Policies Principles of consolidation: All majority-owned subsidiaries are included in the Company’s consolidated financial statements, with appropriate elimination of intercompany balances and transactions. Investments in associated companies (less than majority-owned and in which the Company has significant influence) are accounted for under the equity method. The Company’s share of net income or losses in these investments in associated companies is included in the C onsolidated Statement of Income. The Company periodically reviews these investments for impairments and, if necessary, would adjust these investments to their fair value when a decline in market value or other impairment indicators are deemed to be other than temporary. See Note 14 of Notes to Consolidated Financial Statements. The Financial Accounting Standards Board’s (“FASB’s”) guidance regarding the consolidation of certain Variable Interest Entities (“VIEs”) generally requires that assets, liabili ties and results of the activities of a VIE be consolidated into the financial statements of the enterprise that is considered the primary beneficiary. The consolidated financial statements include the accounts of the Company and all of its subsidiaries i n which a controlling interest is maintained and would include any VIEs if the Company was the primary beneficiary pursuant to the provisions of the applicable guidance. Translation of foreign currency: Assets and liabilities of non-U.S. subsidiaries and a ssociated comp anies are translated into U.S. d ollars at the respective rates of exchange prevailing at the end of the year. Income and expense accounts are translated at average exchange rates prevailing during the year. Translation adjustments resulting from this process are recorded directly in equity as accumulated other comprehensive (loss) income (“AOCI”) and will be included as income or expense only upon sale or liquidation of the underlying investment. Generally, all of the Company’s non-U.S. sub sidiaries use their local currency as their functional currency. Cash and cash equivalents: The Company invests temporary and excess funds in money market securities and financial instruments having maturities typically within 90 days. The Company conside rs all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company has not experienced losses from the aforementioned investments. Inventories: Inventories are valued at the lower of cost or market value, and are valued using the first-in, first-out (“FIFO”) method. See Note 11 of Notes to Consolidated Financial Statements. Long-lived assets: Property, plant and equipment are stated at cost. Depreciation is computed using the straight-line method on a n individual asset basis over the following estimated useful lives: building s and improvements, 10 to 45 years; and machinery an d equipment, 1 to 15 years. The carrying value s of long-lived assets are evaluated whenever ch anges in circumstances or current events indicate the carrying amount of such assets may not be recoverable. An estimate of undiscounted cash flows produced by the asset, or the appropriate group of assets, is compared with the carrying value to determine whether an impairment exists. If necessary, the Company recognizes an impairment loss for the difference between the carrying amount of the assets and their estimated fair value. Fair value is based on current and anticipated future cash flows. Upon sa le or other dispositions of long-lived assets, the applicable amounts of asset cost and accumulated depreciation are removed from the accounts and the net amount, less proceeds from disposals, is recorded in the Consolidated Statements of I ncome. Expendit ures for renewals or improvements that increase the estimated useful life or capacity of the assets are capitalized, whereas expenditures for repairs and maintenan ce are expensed when incurred. See Note 12 of Notes to Consolidated Financial Statements. Capitalized software: The Company capitalizes certain costs in connection with developing or obtaining software for internal use. These costs are amortized over a period of 3 to 5 years once the assets are ready for their intended use. In connection with the implementations and upgrades to the Company’s global transaction, consolidation and other related systems, approximatel y $1,289 and $1,350 of net costs were capitalized in property, plant and equipment on the Company’s December 31, 2015 and 2014 Consolidated Balance Sheets, respectively. Goodwill and other intangible assets: The Company records goodwill, definite-lived intangible assets and indefinite-lived intangible assets at fair value at the date of acq uisition. Goodwill and indefinite-lived intangible assets are not amortized, but tested for impairment at least annually. These tests will be performed more frequently if triggering events indicate potential impairment. Definite-lived intangible assets a re amortized over their estimated useful lives, gen erally for periods ranging from 4 to 20 years. The Company continually evaluates the reasonableness of the useful lives of these assets, consistent with the discussion of long-lived asset s, above. See Note 13 of Notes to Consolidated Financial Statements. Revenue recognition: The Company recognizes revenue in accordance with the terms of the underlying agreements, when title and risk of loss have been transferred, when collectability is reasonably assured, and when pricing is fixed or determinable. For the Company, t his generally occurs when products are shipped to customers or, for consignment-type arrangements, upon usage by the customer and when services are performed. License fee s and royalties are included in other income when recognized in accordance with their agreed-upon terms, when performance obligations are satisfied, when the amount is fixed or determinable, and when collectability is r easonably assured. As part of the Company’s chemical management services, certain third-party product sales to customers are managed by the Company. Where the Company acts as a principal, revenues are recognized on a gross reporting basis at the selling price negotiated with its customers. Where the Company acts as an agent, such revenue is recorded using net reporting as service revenue at the amount of the administrative fee earned by the Company for ordering the goods. Third-party products transferre d under arrangements resulting in net reporti ng totaled $48,580 , $46,844 and $41,553 for 2015 , 2014 and 2013 , respectively. Accounts receivable and allowance for doubtful accounts: Trade accounts receivable subject the Comp any to credit risk. Trade accounts receivable are recorded at the invoiced amount and generally do not bear interest. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses with its existing accounts re ceivable. Reserves for customers filing for bankruptcy protection are generally established at 75-100% of the amount outstanding at the bankruptcy filing date. However, initially establishing a reserve and the amount thereto is dependent on the Company’s evaluation of likely proceeds to be received from the bankruptcy process, which could result in the Company recognizing minimal or no reserve at the date of bankruptcy. Large and/or financially distressed customers are generally reserved for on a specifi c review basis while a general reserve is established for other customers based on historical experience. The Company performs a formal review of its allowance for doubtful accounts quarterly. Account balances are charged off against the allowance when t he Company feels it is probable the receivable will not be recovered. The Company does not have any off-balance-sheet credit exposure related to its customers. During 2015 , the Company’s five largest customers accounted for approximately 18% of its consolidated net sales with the largest customer ( Arcelor -Mittal Group) accounting for approximately 8% of the Company’s consolidated net sales. See Note 10 of Notes to Consolidated Financial Statements. Research and development costs: Research and development costs are expensed as incurred and are included in selling, general and administrative expenses (“SG&A”) . Research and development exp enses were $22,090 , $22,134 and $21,578 in 2015 , 2014 and 2013 , respectively. Environmental liabilities and expenditures: Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. If there is a range of est imated liability and no amount in that range is considered more probable than another, then the Company records the lowest amount in the range in accordance with generally accepted accounting principles. Accrued liabilities are exclusive of claims against third parties and are not discounted. Environmental costs and remediation costs are capitalized if the costs extend the life, increase the capacity or improve safety or efficiency of the property from the date acquired or constructed, and/or mitigate or p reven t contamination in the future. See Note 23 of Notes to Consolidated Financial Statements. Asset retirement obligations: The Company follows the FASB’s guidance regarding asset retirement obligations, which addresses the accounting and reporting f or obligations associated with the retirement of tangible long-lived assets and the associated retirement costs. Also, the Company follows the FASB’s guidance for conditional asset retirement obligations (“CARO”), which relates to legal obligations to per form an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event that may or may not be within the control of the entity. In accordance with this guidance, the Company records a liability when there is enough information regarding the timing of the CARO to perform a probability-weighted discounted cash flow analysis. At December 31, 2015 and 2014 , the Company had limited exposure to such obligations and had immaterial liabilities recorde d for such on its Consolidated Balance Sheets. Pension and other postretirement benefits: The Company maintains various noncontributory retirement plans, the largest of which is in the U.S., covering substantially all of its employees in the U.S. and certa in other countries. The plans of the Company’s subsidiaries in The Netherlands, the United Kingdom (“U.K.”) , Mexico and Sweden are subject to the provisions of FASB’s guidance regarding employers’ accounting for defined benefit pension plans. The plans o f the remaining non-U.S. subsidiaries are, for the most part, either fully insured or integrated with the local governments’ plans and are not subject to the provisions of the guidance. The guidance requires that employers recognize on a prospective basis the funded status of their defined benefit pension and other postretirement plans on their consolidated balance sheet and, also, recognize as a component of other comprehensive income, net of tax, the gains or losses and prior service costs or credits tha t arise during the period but are not recognized as components of net periodic benefit cost. The Company’s U.S. pension plan year ends on November 30 and the measurement date is December 31. The measurement date for the Company’s other postretirement ben efits plan is December 31. The Company’s pension investment policy is designed to ensure that pension assets are invested in a manner consistent with meeting the future benefit obligations of the pension plans and maintaining compliance with various laws and regulations including the Employee Retirement Income Security Act of 1974 (“ERISA”). The Company establishes strategic asset allocation percentage targets and appropriate benchmarks for significant asset classes with the aim of achieving a prudent b alance between return and risk. The Company’s investment horizon is generally long term, and, accordingly, the target asset allocations encompass a long-term perspective of capital markets, expected risk and return and perceived future economic conditions while also considering the profile of plan liabilities. To the extent feasible, the short-term investment portfolio is managed to immunize the short-term obligations, the intermediate portfolio duration is immunized to reduce the risk of volatility in in termediate plan distributions, and the total return portfolio is expected to maximize the long-term real growth of plan assets. The critical investment principles of diversification, assessment of risk and targeting the optimal expected returns for given levels of risk are applied. The Company’s investment guidelines prohibit use of securities such as letter stock and other unregistered securities, commodities or commodity contracts, short sales, margin transactions, private placements (unless specificall y addressed by addendum), or any derivatives, options or futures for the purpose of portfolio leveraging. The target asset allocation is reviewed periodically and is determined based on a long-term projection of capital market outcomes, inflation rates, fixed income yields, returns, volatilities and correlation relationships. The interaction between plan assets and benefit obligations is periodically studied to assist in establishing such strategic asset allocation targets. Asset performance is monitor ed with an overall expectation that plan assets will meet or exceed benchmark performance over rolling five-year periods. The Company’s pension committee, as authorized by the Company’s Board of Directors, has discretion to manage the assets within establ ished asset allocation ranges approved by senior management of the Company. As of December 31, 2015 , the plan’s investments were in compliance with all approved ranges of asset allocations. See Note 18 of Notes to Consolidated Financial Statem ents. Comprehensive income (loss): The Company presents other comprehensive income (loss) in its Statement of Comprehensive Income. The Company follows the FASB’s guidance regarding the disclosure of reclas sifications from AOCI which requires the disclosu re of significant amounts reclassified from each component of AOCI, the related tax amounts and the income statement line items affected by such reclassifications. The Company elected to present the information in its Notes to the Consolidated Financial S tatements. See Note 20 of Notes to Consolidated Financial Statements. Income taxes and uncertain tax positions: The provision for income taxes is determined using the asset and liability approach of accounting for income taxes. Under this approach, de ferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes represents income taxes paid or payable for the current year and the change in d eferred taxes during the year. Deferred taxes result from differences between the financial and tax bases of the Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are re corded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. The FASB’s guidance regarding accounting for uncertainty in income taxes prescribes the recognition threshold and measurement attributes for fina ncial statement recognition and measurement of tax positions taken or expected to be taken on a tax return. The guidance further requires the determination of whether the benefits of tax positions will be more likely than not sustained upon audit based up on the technical merits of the tax position. For tax positions that are determined to be more likely than not sustained upon audit, a company recognizes the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settleme nt in the financial statements. For tax positions that are not determined to be more likely than not sustained upon audit, a company does not recognize any portion of the benefit in the financial statements. Additionally, the Company monitors and adjusts for derecognition , classification, and penalties and interest in interim periods, with appropriate disclosure and transition thereto . A lso , the amount of interest expense and income related to uncertain tax positions is computed by applying the applicabl e statutory rate of interest to the difference between the tax position recognized, including timing differences, and the amount previously taken or expected to be taken in a tax return. The Company’s continuing practice is to recognize interest and/or pe nalties related to income tax matters in income tax expense. Finally, when applicable, t he Company net s its liability for unrecognized tax benefits against deferred tax assets related to net operating losses or other tax credit carryforwards that would ap ply if the uncertain tax position were settled for the presumed amount at the balance sheet date. See Note 8 of Notes to Consolidated Financial Statements. Derivatives: The Company is exposed to the impact of changes in interest rates, foreign currenc y fluctuations, changes in commodity prices and credit risk. The Company is currently not using derivative instruments to mitigate the risks associated with foreign currency fluctuations, changes in commodity prices or credit risk, but has used derivative financial instruments primarily for purposes of hedging exposures to fluctuations in interest rates in the past. When used, the Company recognized all derivatives on its balance sheet at fair value. For derivative instruments designated as cash flow hed ges, the effective portion of any hedge would be reported in AOCI until it was cleared to earnings during the same period in which the hedged item affected earnings. The Company currently uses no derivative instruments designated as hedges and , also, has not entered into derivative contracts for trading or speculative purposes. Fair value measurements: The Company utilizes the FASB’s guidance regarding fair value measurements, which establishes a common definition for fair value to be applied to guidance requiring use of fair value, establishes a framework for measuring fair value and expands disclosure about such fair value measurements. Specifically, the guidance utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into thr ee broad levels. See Note 22 of Notes to Consolidated Financial Statements. The following is a brief description of those three levels: • Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities. • Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. • Level 3: Unobservable inputs that reflect the reporting entity's own assumptions. Stock-based compensation: The Company applies the FASB’s guidance regarding share-based payments, which requires the recognition of the fair value of stock-based compensation as a component of expense. The Company has a long-term incentive program (“LTIP”) for key employees which provides for the granting of options to purchase stock at prices not less than its market value on the date of the grant. Most options become exercisable between one and three years after the date of the grant for a period of time determined by the Company, but not to exceed seven years from the date of grant. Restricted stock awards and r estricted s tock u nits (“RSU”) issued under the LTIP program are generally subject to time vesting over a one to five-year period. In ad dition, as part of the Company’s Global Annual Incentive Plan (“GAIP”), nonvested shares may be issued to key employees, which generally vest over a two to five-year period. Based on historical experience, the Company has assumed a forfeiture rate of 13% on its nonvested stock awards. The Company will record additional expense if the actual forfeiture rate is lower than estimated, and will record a recovery of prior expense if the actual forfeiture is higher than estimated. See Note 6 of Notes to Con solidated Financial Statements. Earnings per share: The Company follows the FASB’s guidance regarding the calculation of earnings per share (“EPS”) for nonvested stock awards with rights to non-forfeitable dividends. The guidance requires nonvested stock awards with rights to non-forfeitable dividends to be included as part of the basic weighted average share calculation under the two-class method. See Note 9 of Notes to Consolidated Financial Statements. Segments: The Company’s reporting segments are the same as the Company’s operating segments. The Company’s reportable operating segments evidence the structure of the Company’s internal organization, the method by which the Company’s resources are allocated and the manner by which the Company assesse s its performance. The Company’s reportable operating segments are organized by geography as follows: ( i ) North America, (ii) Europe, Middle East and Africa (“EMEA”), (iii) Asia/Pacific and (iv) South America. See Note 5 of Notes to Consolidated Fina ncial Statements. Business combinations: The Company accounts for business combinations under the acquisition method of accounting. This method requires the recording of acquired assets, including separately identifiable intangible assets, and assumed liabilities at their respective acquisition date estimated fair values. Any excess of the purchase price over the estimated fair value of the identifiable net assets acquired is recorded as goodwill. The determination of the estimated fair value of assets acquired and liabi lities assumed requires significant estimates and assumptions. Based on the assessment of additional information during the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the estimated fair value of assets acquired and liabilities as sumed. See Note 21 of Notes to Consolidated Financial Statements. Restructuring activities: Restructuring programs consist of employee severance, rationalization of manufacturing or other facilities and other related items. To account for such programs , the Company applies FASB’s guidance regarding exit or disposal cost obligations. This guidance requires that a liability for a cost associated with an exit or disposal activity be recognized when the liability is incurred, is estimable, and payment is probable. See Note 4 of Notes to Consolidated Financial Statements. Reclassifications : Certain information has been reclassified to conform to the current year presentation. Accounting estimates: The prepa ration of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilitie s and disclosure of contingencies at the date of the fina ncial statements and the reported amounts of net sales and expens es during the reporting period. Actual results c ould differ from such estimates.

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
Description Of New Accounting Pronouncements Not Yet Adopted [Text Block]	Note 2 – Recently Issued Accounting Standards The FASB issued an accounting standard update in November 2015 regarding the classification of deferred taxes on the balance sheet. The update requires that all deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. The update does not change the existing requirement that only permits offsetting within a jurisdiction. The guidance within this accounting standards update is effective for annual and interim periods beginning after December 15, 2016, and may be applied either prospectively, for all deferred tax assets and liabilities, or retrospectively. Early adoption is permitted. The Company has not early adopted and is cu rrently evaluating the effects of this guidance but does not expect a material impact. The FASB issued an accounting standard update in September 2015 regarding the accounting and disclosure for measurement period adjustments for business combinations. Th e update requires that the cumulative impact of a measurement period adjustment be recognized in the reporting period in which the adjustment is identified, rather than restating prior period financial statements. The guidance within this accounting stand ard update is effective for annual and interim periods beginning after December 15, 2015, and should be applied on a prospective basis to adjustments to provisional amounts that occur after the effective date, with earlier application permitted for financi al statements that have not been issued. As of and for the year ended December 31, 2015 the Company early adopted this guidance without a material impact. The FASB issued an accounting standard update in July 2015 regarding simplifying the measurement of inventory. The guidance is applicable for entities that measure inventory using the FIFO or average cost methods. Specifically, the update requires that inventory be measured at lower of cost or net realizable value. Net realizable value is the estimate d selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The amendments in this update are effective for fiscal years beginning after December 15, 2016, including interim periods wit hin those fiscal years. This guidance should be applied prospectively with early adoption permitted. The Company has not early adopted and is currently evaluating the effects of this guidance but does not expect a material impact. The FASB issued an acco unting standard update in May 2015 regarding the required disclosures for entities that elect to measure the fair value of certain investments using the net asset value per share (or its equivalent) practical expedient in accordance with the fair value mea surement authoritative guidance. The update removes the requirement to categorize within the fair value hierarchy, and, also limits the requirement to make certain other disclosures, for all such investments. The amendments in this update are effective f or fiscal years beginning after December 15, 2015, and interim periods within those fiscal years, and should be applied on a retrospective basis for the periods presented. Early adoption is permitted. The Company has not early adopted and is currently ev aluating the effects of this guidance but does not expect a material impact. The FASB issued an accounting standard update in April 2015 regarding the presentation of debt issuance costs on the balance sheet. The update requires capitalized debt issuance costs be presented on the balance sheet as a reduction to debt, rather than recorded as a separate asset. The amendments in this update are effective for annual and interim periods beginning after December 15, 2015 and should be applied on a retrospective basis for the periods presented. Early adoption is permitted. Also, in June 2015, the SEC staff announced that the guidance within this accounting standard update was not applicable to revolving debt arrangements or credit facilities. The Company has n ot early adopted and is currently evaluating the effects of this guidance, and the SEC’s announcement, but does not expect a material impact. The FASB issued an accounting standard update in May 2014 regarding the accounting for and disclosure of revenue r ecognition. Specifically, the update outlined a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers, which will be common to both U.S. GAAP and International Financial Reporting Standards (“IFRS”) . The guidance was effective for annual and interim periods beginning after December 15, 2016, which allowed for full retrospective adoption of prior period data or a modified retrospective adoption. Early adoption was not permitted. In August 2015, the FASB issued an accounting standard update to delay the effective date of the new revenue standard by one year, or, in other words, to be effective for annual and interim periods beginning after December 15, 2017. Entities will be permitted to adopt the n ew revenue standard early but not before the original effective date. The Company is currently evaluating the effects of this guidance.

Accounting Changes And Error Corrections [Abstract]
Accounting Changes and Error Corrections [Text Block]	Note 3 – Out-of-Period Adjustment During 2012, the Company reassessed its ability to significantly influence the operating and financial policies of its captive in surance equity affiliate, Primex , Ltd. (“ Primex ”) . Based on its ownership percentage and other factors, the Company determined that, during 2012, the Company obtained the ability to significantly influence Primex and, as a result, changed its method of accounting fr om the cost to equity method. During the first quarter of 2013, the Company identified errors in Primex’s estimated 2012 financial statements, which primarily related to a reinsurance contract held by Primex . The identified errors resulted in a cumulative $1,038 understatement of the Company ’s equity in net income from associated companies for the year ended December 31, 2012. The Company corrected the errors related to Primex in the first quarter of 2013, which had the net effect of increasing equity in net income from associated companies by $ 1,038 for the three months ended March 31, 2013 and the year ended December 31, 2013. The Company did not believe this adjustment wa s material to its consolidated financial statements for the year ended December 31, 2012 or to the Company’s results fo r the year ended December 31, 2013 and, therefore, did not rest ate any prior period amounts.

Consistent with prior years, the Company granted stock options under its LTIP plan that are subject only to time vesting over a three-year p eriod in the first quarters of 2012 , 2013 , 2014 and 2015 . Also, in connection with a transition of key employees during the second quarter of 2012, stock options were granted that are also only subject to time vesting over a three-year period. For the purposes of determining the fair value of stock option awards, the Company uses t he Black-Scholes option pricing model and the assumptions set forth in the table below: For the Year Ended December 31, June 30, 2015 2014 2013 2012 2012 Number of stock options granted 38,698 37,048 29,302 37,965 2,192 Dividend yield 1.55 % 2.00 % 2.49 % 3.09 % 2.69 % Expected volatility 36.32 % 43.34 % 57.28 % 69.90 % 69.09 % Risk-free interest rate 1.22 % 1.22 % 0.63 % 0.61 % 0.58 % Expected term (years) 4.0 4.0 4.0 4.0 4.0 These awards are being amortized on a straight-line b asis over the respective vesting period of each award.

The Company adjusts the grant date fair value for expected forfeitures based on historical experience for similar awards. As of December 31, 2015 , unrecognized compensation expense related to these awards was $3,784 , to be recognized over a weighted averag e remaining period of 1.73 years. Activity of nonvested restricted stock units granted under the Company’s LTIP p lan is shown below: Weighted Average Grant Number of Date Fair Value Units (per unit) Nonvested awards, December 31, 2014 7,158 $ 61.03 Granted 1,450 $ 87.30 Vested (2,434) $ 43.45 Nonvested awards, December 31, 2015 6,174 $ 74.14 The fair value of the nonvested restricted stock units is based on the trading price of the Company’s common stock on the date of grant. The Company adjusts the grant date fair value for expected forfeitures based on historical experience for similar awards. As of December 31, 2015 , unrecognized compensation expense related to these awards was $165 to be recognized over a weighted average remaining period of 1.60 years. Employee Stock Purchase Plan In 2000, the Board adopted an Employee Stock Purchase Plan (“ESPP”) whereby employees may purchase Company stock through a payroll deduction plan. Purchases are made from the plan and credited to each participant’s a ccount at the end of each month ( the “Investment Date” ). The purchase price of the stock is 85 % of the fair market value on the Investment Date. The plan is compensatory and the 15 % discount is expensed on the Investment Date. All employees, including officers, are eligible to participate in this plan. A participant may withdraw all uninvested payment balances credited to a participant’s account at any time . An employee whose stock ownership of the Company exceeds five percent of the outstanding common stock is not eligible to participate in this plan. 2013 Director Stock Ownership Plan In 2013, the Company adopted the 2013 Director Stock Ownership Plan (the “Plan”) , to encourage the Directors to increase their investment in the Company , which was approved at the Company’s May 2013 shareholders’ meeting. The Plan authorizes the issuance of up to 75,000 shares of Quaker common stock in accordance with the terms of the Plan in payment of all or a portion of the annual cash retainer payable to each of the Company’s non-employee directors in 2013 and subsequent years during the term of the Plan.

In addition, the Company has foreign tax loss carryforwards of $10,538 of which $47 expires in 2016 , $150 expires in 2017 , $479 expires in 2018 , $374 expires in 2019 , $93 expires in 2020 , $354 expires in 2021 , $145 expires in 2022 , $6 expires in 2023 , $62 expires in 2024 , $103 expires in 2025 , $1,510 expires in 2030 , and $59 expires in 2035 ; the remaining foreign tax losses have no expiration dates. A partial valuation allowance has been established with respect to the tax benefit of these losses for $961 . U.S. income taxes have not been provided on the undistributed earnings of non-U.S. subsidiaries because it is the Company’s intention to continue to reinvest these earnings in those subsidiaries to support growth initiatives. U.S. and foreign income t axes that would be payable if such earnings were distributed may be lower than the amount computed at the U.S. statutory rate due to the availability of tax credits. The amount of such undistributed earnings at December 31, 2015 was approximately $203,000 . Any income tax liability, which might result from ultimate remittance of these earnings, is expected to be substantially offset by foreign tax credits. It is currently impractical to estimate any such incremental tax expense. As of December 31, 2015 , the Company’s cumulative liability for gross unrecognized tax benefits was $11,032 . The Company had accrued $1,890 for cumulative penalties and $1,465 for cumulative interest at December 31, 2015 . As of December 31, 2014 , the Company’s cumulative liability for gross unrecognized tax benefits was $11,845 . The Company had accrued $1,845 for cumulative penalties and $1,868 for cumulative interest at December 31, 2014 . The Company continues to recognize interest and penalties associated with uncertain tax positions as a component of taxes on income before equity in net income of associated companies in its Consolidated Statement of Income. The Company r ecognized $225 for penalties and ($226) for interest (net of expirations and settlements) on its 2015 Consolidated Statement of Income, ($26) for penalties and ($31) for interest (net of expirations and settlements) on its 2014 Consolidated Statement of Income and $392 for penalties and ($247) for interest (net of expirations and settlements) on its 2013 Consolidated Statement of Income. The Company estimates that during the year end ing December 31, 2016 , it will reduce its cumulative liability for gross unrecognized tax benefits by approximately $1,900 to $2,000 due to the expiration of the statute of limitations with regard to certain tax positions. This estimat ed reduction in the cumulative liability for unrecognized tax benefits does not consider any increase in liability for unrecognized tax benefits with regard to existing tax positions or any increase in cumulative liability for unrecognized tax benefits wit h regard to new tax positions for the year ending December 31, 2016 . The Company and its subsidiaries are subject to U.S. Federal income tax, as well as the income tax of various state and foreign tax jurisdictions. Tax years that remain subject t o examination by major tax jurisdictions include Brazil from 2000, Italy from 2007, the Netherlands from 2009, the United Kingdom from 2010, Spain from 2011, China and the United States from 2012, and various domestic state tax jurisdictions from 1993 . Dur ing 2012, the Italian tax authorities initiated a transfer pricing audit of the Company’s Italian subsidiary, Quaker Italia S.r.l ., relating to the tax years 2007, 2008, 2009 and 2010. During the second quarter of 2015, the Italian tax authorities complet ed an audit of the Company’s Italian subsidiary, Quaker Chemical S.r.l . (formerly NP Coil Dexter Industries, S.r.l .), relating to the tax years 2010, 2011, 2012 and 2013, and proposed adjustments for those years. In the fourth quarter of 2015, the Company paid the tax liability for these proposed adjustments in full. In the fourth quarter of 2015, the Dutch tax authorities assessed the Company’s Dutch subsidiary for additional income taxes related to the 2011 tax year and the Dutch subsidiary filed a prot est of the assessment. In January 2016, the French tax authorities gave notice that they were auditing the Company’s French subsidiary. In February 2016, the Italian tax authorities gave notice that they were starting an audit of the 2013 tax year for Qu aker Italia S.r.l . As of December 31, 2015 , the Company believes it has adequate reserves, where merited, for uncertain tax positions with respect to these audits. A reconciliation of the beginning and ending amounts of unrecognized tax benefits f or the years ended December 31, 2015 , 2014 and 2013 , respectively, is as follows: 2015 2014 2013 Unrecognized tax benefits at January 1 $ 11,845 $ 12,596 $ 12,410 (Decrease) increase in unrecognized tax benefits taken in prior periods (416) (93) 83 Increase in unrecognized tax benefits taken in current period 2,512 2,678 2,182 (Decrease) in unrecognized tax benefits due to lapse of statute of limitations (1,924) (2,078) (2,485) (Decrease) increase due to foreign exchange rates (985) (1,258) 406 Unrecognized tax benefits at December 31 $ 11,032 $ 11,845 $ 12,596 The amount of unrecognized tax benefits above that, if recognized, would impact the Company’s tax expense and effective tax rate is $1,137 , $1,066 and $1,194 in 2015 , 2014 and 2013 , respectively.

The Company continually evaluates the financial performance, economic conditions and other relevant developments in assessing if an interim period impairment test for one or more of its reporting units is necessary. The Company completed its annua l impairment assessment as of the end of the third quarter of 2015 and no impairment charge was warranted. The estimated fair value of each of the Company’s reporting units substantially exceeded its carrying value, with no reporting unit at risk for fail ing step one of the goodwill impairment test.

Investments in Associated Companies [Abstract]
Investments in Associated Companies [Text Block]	Note 14 – Investments in Associated Companies As of December 31, 2015 , the Company held a 50% investment in and had significant influence over Kelko Quaker Chemical, S.A. (Venezuela), Nippon Quaker Chemical, Ltd. (Japan) and Kelko Quaker Chemical S.A. (Panama) and held a 33% investment in and had significant influence over Primex , Ltd. (Barbados). The carrying amount of the Company’s equity investments at December 31, 2015 was $20,354 , which includes its investm ents of $14,895 in Primex , Ltd. (Barbados); $5,014 in Nippon Quaker Chemical, Ltd. (Japan); $247 in Kelko Quaker Chemical, S.A. (Panama) ; and $198 in Kelko Quaker Chemical, S.A. (Venezuela). In 2003, the Venezuela government suspen ded the free exchange of bolivar fuerte (“ BsF ”) for foreign currency and implemented certain foreign exchange controls that served to centralize the purchase and sale of foreign currency within the country. As of December 31, 2014 , there were thre e legally available exchange rates in Venezuela, the CADIVI (or the official rate, 6.3 BsF per U.S. dollar), the SICAD I (approximately 12 BsF per U.S. dollar) and the SICAD II (approximately 52 BsF per U.S. dollar). In the first quarter of 2015, the Vene zuela government announced changes to its exchange controls. There continues to be three exchange mechanisms in Venezuela; however, they now consist of the CADIVI, a combined SICAD I and SICAD II auction mechanism (the “SICAD”) and a newly created, margin al currency system (the “SIMADI”). The CADIVI exchange largely remained the same, except that the government further restricted what products qualify and can, therefore, legally be imported or traded under this exchange. The government has not fully disc losed who can access or trade on the newly formed combined SICAD market and minimal related auctions have occurred to date. Finally, the newly created SIMADI is legally available to all parties, however, at significantly higher exchange rates than the CAD IVI or SICAD. As of December 31, 2015 , the published rate for the SIMADI is approximately 198 BsF per U.S. dollar. Venezuela’s economy has been considered hyper inflationary under U.S. GAAP since 2010, at which time the Company’s Venezuela equity affiliate, Kelko Quaker Chemical, S.A. (“ Kelko Venezuela”), changed its functional currency to the U.S. dollar. Accordingly, all gains and losses resulting from the remeasurement of Kelko Venezuela’s monetary assets and liabilities to the CADIVI, SICAD, S IMADI, or other published exchange rates are required to be recorded directly to the Consolidated Statement of Income. As of December 31, 2014, Kelko Venezuela had access to the CADIVI for imported goods, had not been invited to participate in any SICAD I auctions and had limited access to the SICAD II mechanism. Accordingly, the Company measured its equity investment and other related assets with Kelko Venezuela at the CADIVI exchange rate at December 31, 2014. In light of the first quarter of 2015 cha nges to Venezuela’s foreign exchange controls and the on-going economic challenges in Venezuela, the Company re-assessed Kelko Venezuela’s access to U.S. dollars, the impact on the operations of Kelko Venezuela, and the impact on the Company’s equity inves tment and other related assets. During the first quarter of 2015, the Company determined that the CADIVI was no longer available to Kelko Venezuela for import transactions. As the government has yet to fully disclose who can access or trade on the SICAD mechanism and minimal related auctions have occurred to date, the Company revalued its equity investment in Kelko Venezuela and other related assets to the SIMADI exchange rate of approximately 193 BsF per U.S. dollar as of March 31, 2015. This resulted i n a charge of approximately $2,806, or $0.21 per diluted share, recorded in the first quarter of 2015. As of December 31, 2015 , the Company’s equity investment in Kelko Venezuela continues to be valued at the SIMADI exchange rate. During the secon d quarter of 2014, the Company recorded a charge of $321, or $0.02 per diluted share, related to the conversion of certain BsF to U.S. d ollars on the historical SICAD II exchange. During the first quarter of 2013, the Venezuela Government announced a deva luation of the BsF , which resulted in a charge of $35 7, or $0.03 per diluted share. Summarized financial information of Kelko Quaker Chemical, S.A. (Venezuela), Nippon Quaker Chemical, Ltd. (Japan) and Kelko Quaker Chemical S.A. (Panama), in the aggregate, is as follows: December 31, 2015 2014 Current Assets $ 36,761 $ 42,828 Noncurrent Assets 606 1,105 Current Liabilities 26,039 28,797 Noncurrent Liabilities 410 397 Year Ended December 31, 2015 2014 2013 Net Sales $ 40,282 $ 48,834 $ 47,226 Gross Margin 12,887 15,698 16,096 Income Before Income Taxes (2,843) 3,546 3,687 Net Income (3,631) 2,263 2,142 During 2015, the Company identified a correction to the presentation of December 31, 2014 summarized financial information. As a result, the Company revised the December 31, 2014 current assets and current liabilities by increasing such amounts by $15,149 each, from previously disclosed amounts. The Company considers such revisions to the prior period to be immaterial. Summarized financial information of Primex , Ltd. is as follows: December 31, 2015 2014 Total Assets $ 105,585 $ 109,259 Total Liabilities 54,534 59,773 Year Ended December 31, 2015 2014 2013 Revenue $ 7,058 $ 10,755 $ 20,895 Income Before Income Taxes 8,407 10,929 25,625 Net Income 6,334 7,352 16,876 During the first quarter of 2013, the Company identified errors in Primex’s estimated 2012 financial statements, which primarily related to a reinsurance contract held by Primex . The identified errors resulted in increases to Primex’s revenue of $4,905, income before taxes of $5,240 and net income of $3,422, which are included in the 2013 summarized financial information for Primex above. The identified errors resulted in a cumulative $1,038 understatement of the Company’s equity in net income from assoc iated companies for the year ended December 31, 2012, which were corrected in the first quarter of 2013.

Due to the restricted nature of the proceeds, a corr esponding deferred credit was established in “Other non-current liabilities” for an equal and offsetting amount, and will remain until the restrictions lapse or the funds are exhausted via payments of claims and costs of defense.

Debt [Text Block]	Note 17 – Debt Debt as of December 31, 2015 and 2014 includes the following : December 31, 2015 2014 Credit facilities $ 62,884 $ 58,421 Industrial development bonds 15,000 15,000 Municipality-related loans 4,098 2,109 Other debt obligations (including capital leases) 119 201 82,101 75,731 Current portion of long-term debt (662) (403) $ 81,439 $ 75,328 Credit facilities The Company’s primary credit line is a $300,000 syndicated multicurrency credit agreement with a group of lenders, which matures in June 2018. The maximum amount available under this credit facility can be increased to $400,000 at the Company’s option if the lenders agree and the Company satisfies certain conditions. Borrowings under this credit facility generally bear interest at a base rate or LIBOR rate plus a margin. At December 31, 2015 and 2014 , the Compa ny had approximately $62,884 and $58,421 outstanding, primarily on this credit facility, at weighted average borrowing rates of 1.38% and 1.16%, respectively. Access to this credit facility is dependent on meeting certain financial, acquisition an d other covenants, but primarily depends on the Company’s consolidated leverage ratio calculation, which cannot exceed 3.50 to 1. As of December 31, 2015 and 2014 , the Company’s consolidated leverage ratio was below 1.0 to 1, respectively, and the Company was also in compliance with all of the other covenants. Industrial development b onds The Company has two fixed rate, industrial development authority demand bonds, with $5,000 due in 2018, bearing interest at a rate of 5.60%, and $10,000 d ue in 2028, bearing interest at a rate of 5.26%. These bonds have similar covenants to the credit facilities noted above.

As of December 31, 2015 and 2014 , there was $1,784 and $2,109 , respectively, outstanding on this loan. With the third quarter of 2015 acquisition of Verkol S.A. (“ Verkol ”), the Company assumed certain loans, issued by the local government, which are either interest-free or bear interest at a subsidized rate. These loans mature periodically, with the last maturity occurring in 2026. The Company recorded these loans at fair value based on market interest rates on the date of acq uisition and continues to measure the loans at amortized cost, recognizing the implicit interest incurred. As of December 31, 2015 , there was $2,314 outstanding for these loans. During the next five years, payments on the Company’s debt, in cluding capital lease maturities, are due as follows: 2016 $ 662 2017 719 2018 66,931 2019 656 2020 651 At December 31, 2015 and 2014 , the amounts at which the Company’s debt is recorded are not materially different from their fair market value.

Under the spot rate approach, benefit obligations have been determined based on application of the spot rates on a given yield curve at each future year to eac h plan's projected cash flows. The use of the spot-rate approach did not have an impact on the Company's 2015 Consolidated Financial Statements. The long-term rates of return on assets were selected from within the reasonable range of rates determined by (a) historical real returns for the asset classes covered by the investment policy and (b) projections of inflation over the long-term period during which benefits are payable to plan participants. See N ote 1 of Notes to Consolidated Financial Statements for further information.

The following is a description of the valuation methodologies used for the investments measured at fair value, including the general classification of such instruments pursuant to the valuation hierarchy: Cash and Cash Equivalents Cash and cash equivalents consist of cash and money market funds and are classified as Level 1 inves tments. Common Stock Common stock is valued based on quoted market prices on an exchange in an active market and is classified as Level 1 investments. Registered Investment Companies The shares of registered investment companies, which represent the net as set values of shares held by the Plan, are valued based on quoted market prices o n an exchange in an active market and are classified as Level 1 investments. Fixed Income Corporate Securities Corporate fixed income securities are valued using third party pricing services which are based on a combi nation of quoted market prices o n an exchange in an active market as well as proprietary pricing models and inputs using observable market data and are classified as Level 2 investments. Fixed Income U.S. and Fo reign Government Securities U.S. and foreign government fixed income securities are valued using third party pricing services which are based on a combi nation of quoted market prices o n an exchange in an active market as well as proprietary pricing models and inputs using observable market data and are classified as Level 2 investments. Pooled Separate Accounts Investments in the U.S. pension plan pooled separate accounts consist of insurance annuity contracts and are valued based on the reported unit val ue at year end. Units of the pooled se parate accounts are not traded o n an exchange or in an active market; however, valuation is based on the underlying investments of the units and are classified as Level 2 investments. Insurance Contract Investments in the foreign pension plan insurance contract are valued at the highest value available for the Company at year end, either the reported cash surrender value of the contract or the vested benefit obligation. Both the cash surrender value and the vested benefit obligation are determined based on unobservable inputs, which are contractually or actuarially determined, regarding returns, fees, the present value of the future cash flows of the contract and benefit obligations. The contract is clas sified as a Level 3 investment. Diversified Equity Securities - Registered Investment Companies Investments in the foreign pension plan diversified equity securities of registered investment companies are based upon the quoted redemption value of shares in the fund owned by the plan at year end. The shares of the fund are not available o n an exchange or in an active market; however, the fair value is determined based on the underlying inve stments in the fund as traded on an exchange in an active market and are classified as Level 2 investments. Fixed Income – Foreign Registered Investment Companies Investments in the foreign pension plan fixed income securities of foreign registered investment companies are based upon the quoted redemption value of shares i n the fund owned by the plan at year end. The shares of the fund are not available o n an exchange or in an active market; however, the fair value is determined based on the underlying investments in the fund as traded on an exchange in an active market an d are classified as Level 2 investments. Real Estate The foreign pension plan’s investment in real estate consists of an investment in a property fund. The fund’s underlying investments consist of real property, which are valued using unobservable inputs. The property fund is classified as a Level 3 investment. Commingled Funds Investments in the foreign pension plan commingled funds represent pooled institutional investments, including primarily investment trusts. As of December 31, 2015, commingled fun ds include d approximately 30 percent of investments in equity , 61 percent of investments in fixed income, and 9 percent of other non-related investments. The comm ingled funds are not available o n an exchange or in an active market; however, the fair value is determined based on the underlying pooled investments. Generally, these und erlying investments are traded o n an exchange in an active market and , therefore, the funds are classified as Level 2 investments. As of December 31, 2015 and 2014 , the U.S. and foreign plans’ investments measured at fair value on a recurring basis were as follows: Fair Value Measurements at December 31, 2015 Total Using Fair Value Hierarchy U.S. Pension Assets Fair Value Level 1 Level 2 Level 3 Cash and cash equivalents $ 753 $ 753 $ — $ — Large capitalization common stock 13,346 13,346 — — Large capitalization registered investment companies 6,363 6,363 — — Small capitalization common stock 773 773 — — Small capitalization registered investment companies 2,333 2,333 — — International developed and emerging markets registered investment companies 5,166 5,166 — — International developed and emerging markets common stock 2,519 2,519 — — Fixed income corporate securities 9,601 — 9,601 — Fixed income registered investment companies 4,147 4,147 — — Fixed income U.S. and foreign government securities 308 — 308 — Pooled separate accounts 1,392 — 1,392 — Total U.S. pension plan assets $ 46,701 $ 35,400 $ 11,301 $ — Fair Value Measurements at December 31, 2015 Total Using Fair Value Hierarchy Foreign Pension Assets Fair Value Level 1 Level 2 Level 3 Cash and cash equivalents $ 7 $ 7 $ — $ — Insurance contract 62,409 — — 62,409 Diversified equity securities - registered investment companies 7,180 — 7,180 — Fixed income - foreign registered investment companies 2,290 — 2,290 — Commingled funds 1,882 — 1,882 — Real estate - registered investment companies 2,388 — — 2,388 Total foreign pension assets $ 76,156 $ 7 $ 11,352 $ 64,797 Total pension assets at fair value $ 122,857 $ 35,407 $ 22,653 $ 64,797 Fair Value Measurements at December 31, 2014 Total Using Fair Value Hierarchy U.S. Pension Assets Fair Value Level 1 Level 2 Level 3 Cash and cash equivalents $ 490 $ 490 $ — $ — Large capitalization common stock 14,956 14,956 — — Large capitalization registered investment companies 6,339 6,339 — — Small capitalization common stock 920 920 — — Small capitalization registered investment companies 2,416 2,416 — — International developed and emerging markets registered investment companies 5,638 5,638 — — International developed and emerging markets common stock 2,600 2,600 — — Fixed income corporate securities 9,848 — 9,848 — Fixed income registered investment companies 4,647 4,647 — — Fixed income U.S. and foreign government securities 406 — 406 — Pooled separate accounts 1,429 — 1,429 — Total U.S. pension plan assets $ 49,689 $ 38,006 $ 11,683 $ — Foreign Pension Assets Cash and cash equivalents $ 76 $ 76 $ — $ — Insurance contract 72,417 — — 72,417 Diversified equity securities - registered investment companies 6,565 — 6,565 — Fixed income - foreign registered investment companies 4,946 — 4,946 — Commingled funds 2,041 — 2,041 — Real estate - registered investment companies 478 — — 478 Total foreign pension assets $ 86,523 $ 76 $ 13,552 $ 72,895 Total pension assets at fair value $ 136,212 $ 38,082 $ 25,235 $ 72,895 Changes in the fair value of the foreign plans’ Level 3 investments during the years ended December 31, 2015 and 2014 were as follows: Insurance Real Estate Contract Fund Total Balance at December 31, 2013 $ 57,175 $ 434 $ 57,609 Purchases 3,044 — 3,044 Settlements (1,705) — (1,705) Unrealized gains 22,802 72 22,874 Currency translation adjustment (8,899) (28) (8,927) Balance at December 31, 2014 72,417 478 72,895 Purchases 953 1,937 2,890 Settlements (1,239) — (1,239) Unrealized (losses) gains (2,402) 60 (2,342) Currency translation adjustment (7,320) (87) (7,407) Balance at December 31, 2015 $ 62,409 $ 2,388 $ 64,797 U.S. pension assets include Company common stock in the amounts of $773 ( 2% of total U.S. plan assets) and $920 ( 2% of total U.S. plan assets) at December 31, 2015 and 2014 , respectively. During 2013, it was discovered that the Company’s subsidiary in the U.K. did not appropriately amend a trust for a legacy change in its pension scheme, as it related to a past retirement age equalization law. Given the lack of an official deed to the pens ion trust, the effec tive date of the change to the s ubsidiary’s pension scheme differed from the Company’s historical beliefs, but the extent of the potential exposure was not estimable.

Equity [Abstract]
Stockholders' Equity Note Disclosure [Text Block]	Note 20 – Equity and Accumulated Other Comprehensive Loss In May 2015, the Company’s Board of Directors authorized a share repurchase program for the repurchase of up to $100,000 of Quaker Chemical Corporation common stock (the “2015 Share Repurchase Program”). The 2015 Share Repurchase Program has no expiration date. The 2015 Share Repurchase Program provides a framework of conditions under which management can repurchase shares of the Company’s common stock. The Company intends to repu rchase shares to at least offset the dilutive impact of shares issued each year as part of its employee benefit and share- based compensation plans, and could repurchase more if the Company considers the share p rice to be an amount that is an advantageou s return for its shareholders. The purchases may be made in the open market or in private and negotiated transactions, in accordance with applicable laws, rules and regulations. In connection with the 2015 Share Repurchase Program, the remaining unutiliz ed 1995 and 2005 Board of Directors authorized share repurchase programs were terminated. In connection with the 2015 Share Repurchase Program, the Company acquired 87,386 shares of common stock for $7,276, during the year ended December 31, 2015 . The Company has elected not to hold treasury shares, and, therefore, has retired the shares as they are repurchased. It is the Company’s accounting policy to record the excess paid over par value as a reduction in retained earnings for all shares repurch ased. The Company has 30,000,000 shares of common stock authorized, with a par value of $1, and 13,288,113 and 13,300,891 shares issued as of December 31, 2015 and 2014 , respectively. The change in shares issued and outstanding during 2 01 5 was primarily related to 87,386 shares repurchased in connection with the 2015 Share Repurchase Program offset by 51,848 shares issued for equity- based compensation plans, 6,084 shares issued for the ESPP and 16,676 shares issued for the exercise of stock options and other employee and director- related share activity . Holders of record of the Company’s common stock for a period of less than 36 consecutive calendar months or less are entitled to one vote per share of common stock. Holders of record of the Company’s common stock for a period greater than 36 consecutive calendar months are entitled to 10 votes per share of common stock. The Company is authorized to issue 10,000,000 shares of preferred stock, $1 par v alue, subject to approval by the Board of Directors. The Board of Directors may designate one or more series of preferred stock and the number of shares, rights, preferences, and limitations of each series. As of December 31, 2015 , no preferred s tock had been issued.

Business Combinations [Abstract]
Business Combination Disclosure [Text Block]	Note 21 – Business Acquisitions In July 2015, the Company acquired Verkol , a leading specialty grease and other lubricants manufacturer based in northern Spain for its EMEA reportable operating segment for approximately 37,737 EUR, or approximately $41,393, which includes a post-closing adjustment of 1,282 EUR, or approximately $1,384, accrued for by the Company as of December 31, 2015 and subsequently paid in January 2016. The purchase included cash acquired of approximately 14,053 EUR, or approxim ately $15,423, and assumed long-term debt of approximately 2,187 EUR, or approximately $2,400. In addition, the Company incurred approximately $2,813, or $0.15 per diluted share, of one-time transaction expenses in the third quarter of 2015, related to th is acquisition. Verkol is a market leader with world-class grease manufacturing capabilities and state-of-the-art research and development facilities, selling products into industrial end markets with a particular strength serving the steel industry. Als o, Verkol brings a unique technology in continuous casting products that will provide the Company with cross-selling opportunities to its global steel customer base. The Company allocated $11,743 of the purchase price to intangible assets, comprised of tr ademarks and formulations, to be amortized over 15 years; a non-compete agreement, to be amortized over 4 years; and customer relationships, to be amortized over 15 years. In addition, the Company recorded $5,165 of goodwill, including the $1,384 post -closing adjustment mentioned above, related to expected value not allocated to other acquired assets, none of which will be tax deductible. As of December 31, 2015, the allocation of the purchase price for the Verkol acquisition has not been finalized and the one-year measurement period has not ended. Further adjustments may be necessary as a result of the Company’s assessment of additional information related to the fair value of assets acquired and liabilities assumed. The following table presents the current allocation of the purchase price of the assets acquired and liabilities assumed: Verkol Acquisition Current assets $ 30,998 Property, plant and equipment 7,941 Intangibles Customer lists and rights to sell 6,146 Trademarks and patents 5,378 Other intangibles 219 Goodwill 5,165 Other long-term assets 158 Total assets purchased 56,005 Current liabilities (6,681) Long-term debt (2,400) Other long-term liabilities (5,531) Total liabilities assumed (14,612) Cash paid for acquisitions $ 41,393 In December 2014, the Company acquired a business that is principally concerned with safety fluid applications for mining sites in its Asia/Pacific reportable operating segment for net consideration of approximately 2,850 Australian dollars, or approximately $2,355. The Company also assumed an additional 300 Australian dollars hold-back of consideration, which was paid out and settled during the fourth quarter of 2015. This acquisition provides a strategic opportunity for Quaker in the core Aus tralian mining market. The Company allocated $1,802 of the purchase price to intangible assets, comprised of trademarks and formulations, to be amortized over 15 years; a non-competition agreement, to be amortized over 5 years; and customer relationships, to be amortized over 15 years. In addition, the Company recorded $1,178 of goodwill, related to expected value not allocated to other acquired assets, none of which will be tax deductible. In November 2014, the Company acquired Binol AB (“ Binol ”), a leading bio-lubricants producer primarily serving the Nordic region for its EMEA reportable operating segment for approximately 136,500 SEK, or approximately $18,536, which is net of 4,400 SEK, or approximately $528, received by the Company as part of a po st-closing adjustment in the first quarter of 2015. The post-closing adjustment recorded in the first quarter of 2015 adjusted the acquisition’s goodwill. This acquisition provides a strategic opportunity for Quaker to leverage Binol's environmentally fr iendly technology and customer-aligned products, including neat oil technology for metalworking applications and biodegradable hydraulic oils, across the Company’s global footprint. The Company allocated $11,805 of the purchase price to intangible assets, comprised of trademarks and formulations, to be amortized over 15 years; a non-competition agreement, to be amortized over 5 years; and customer relationships, to be amortized over 14 years. In addition, the Company recorded $5,726 of goodwill, net of th e $528 post-closing adjustment mentioned above, related to expected value not allocated to other acquired assets, none of which will be tax deductible. In August 2014, the Company acquired ECLI Products, LLC (“ECLI”), a specialty grease manufacturer for i ts North American reportable operating segment for approximately $53,145, including certain post-closing adjustments. ECLI specializes in greases for OEM first-fill customers across several industry sectors, including automotive, industrial, aerospace/mil itary, electronics, office automation and natural resources. This acquisition complements Quaker’s entry into the specialty grease market that began in 2010, and, also, provides an opportunity to leverage Quaker's global footprint with its current market expertise. The Company allocated $31,050 of the purchase price to intangible assets, comprised of trademarks and formulations, to be amortized over 10 years; customer relationships, to be amortized over 15 years; and a non-compete agreement, to be amortiz ed over 5 years. In addition, the Company recorded $14,642 of goodwill, related to expected value not allocated to other acquired assets, all of which will be tax deductible. During 2015, the Company identified and recorded certain adjustments to the allocations of the purchase price for certain 2014 acquisitions. These adjustments were the result of the Company assessing additional information related to assets acquired and liabilities assumed during the one-year measurement period following each acquisition. As of December 31, 2015 , the allocations of the purchase price for all of the Company’s 2014 acquisitions have been finalized. The following table presents the final allocation of the purchase price of the assets acquired and liabilities assumed in all of the Company’s acquisitions in 2014: 2014 Acquisitions Current assets $ 12,413 Property, plant and equipment 4,158 Intangibles Customer lists and rights to sell 30,924 Trademarks and patents 12,606 Other intangibles 1,127 Goodwill 21,546 Other long-term assets 198 Total assets purchased 82,972 Current liabilities (4,562) Long-term liabilities (4,374) Total liabilities assumed (8,936) Cash paid for acquisitions $ 74,036 Included in the 2014 acquisition s was approximately $ 1,037 of cash acquired. Additionally, i n June 2014, the Company acquired the remaining 49% ownership interest in its Australian affiliate, Quaker Chemical (Australasia) Pty. Limited ("QCA") for 8,000 Australian d ollars, or approximately $7,577, from its joint venture partner, Nuplex Industries. QCA is a part of the Company’s Asia/Pacific reportable operating segment. This acquisition further strengthens Quaker’s position in Australia , and allows the Company to simplify its overall corporate structure and improve its organizational efficiencies. As this acquisition was a change in an existing controlling ownership, the Company recorded $6,450 of excess purchase price over the carrying value of the no ncontrolling interest in Additional Paid in Capital. In May 2013, the Company acquired a business that primarily related to tin plating for its North American reportable operating segment for net consider ation of approximately $1,831. In January 2013, the Company acquired a chemical milling maskants distribution network for net consideration of approximately $647, which was assigned to the North America reportable operating segment. The Comp any also assumed a hold-back of consideration for potential in demnity obligations, which was paid to the former shareholders during the first quarter of 2014. In December 2010, the Company acquired Summit Lubricants, Inc., which manufactures and distributes specialty greases and lubricants, for approximately $29,83 3, including certain post-closing adjustments finalized in 2011. Liabilities assumed included an earnout to be paid to the former shareholders if certain earnings targets were met by the end of 2013. During 2013, the Company recorded net increases to oth er income of approximately $497 in its Consolidated Statement of Income to finalize the Company’s estimate of the fair value of this contingent consideration liability , which was settled and paid during the second quarter of 2014 with a payment to the form er shareholder of approximately $4,709. The results of operations of the acquired businesses and assets are included in the Consolidated Statements of Income from their respective acquisition dates. Transaction expenses associated with these acquisition s are included in SG&A in the Company’s Consolidated Statements of Income. Certain pro forma and other information is not presented, as the operations of the acquired businesses are not material to the overall operations of the Company for the periods pre sented.

Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies Disclosure [Text Block]	Note 23 – Commitments and Contingencies In 1992, the Company identified certain soil and groundwater contamination at AC Products, Inc. (“ACP”), a wholly owned subsidiary. In voluntary coordination with the Santa Ana California Regional Water Quality Board (“SACRWQB”), ACP has been remediating the contamination, the principal contaminant of which is perchloroethylene (“PERC”). In 2004, the Orange County Water District (“OCWD”) filed a civil complaint against ACP and other parties seeking to recover compensatory and other damages related to the investigation and remediation of the contamination in the groundwater. Pursuant to a settlement agreement with OCWD, ACP agreed, among other things, to operate the two groundwater treatment systems to hydraulically contain groundwater contamination emanat ing from ACP’s site until the concentrations of PERC released by ACP fell below the current Federal maximum contaminant level for four consecutive quarterly sampling events. In February 2014, ACP ceased operation at one of its two groundwater treatment sy stems, as it had met the above condition for closure. Based on the most recent modeling, it is estimated that the remaining system will operate for another one to three years . As of December 31, 2015 , the Company believes that the range of potenti al-known liabilities associated with the balance of ACP water remediation program is approximately $360 to $1,030 , for which the Company has sufficient reserves. The low and high ends of the range are based on the length of operation of the tr eatment system as determined by groundwater modeling. Costs of operation include the operation and maintenance of the extraction well, groundwater monitoring and program management. The Company believes, although there can be no assurance regarding the outcome of other unrelated environmental matters, that it has made adequate accruals for costs associated with other environmental problems of which it is aware. Approximately $295 and $173 was accrued at December 31, 2015 and 2014 , respectively, to provide for such anticipated future environmental assessments and remediation costs. An inactive subsidiary of the Company that was acquired in 1978 sold certain products containing asbestos, primarily on an installed basis, and is among the defendants in numerous lawsuits alleging injury due to exposure to asbestos. The subsidiary discontinued operations in 1991 and has no remaining assets other than proceeds received from insurance settlements. To date, the overwhelming major ity of these claims have been disposed of without payment and there have been no adverse judgments against the subsidiary. Based on a continued analysis of the existing and anticipated future claims against this subsidiary, it is currently projected that the subsidiary’s total liability over the next 50 years for these claims is less than $3,000 ( excluding costs of defense). Although the Company has also been named as a defendant in certain of these cases, no claims have been actively pursued against the Company, and the Company has not contributed to the defense or settlement of any of these cases pursued against the subsidiary. These cases were handled by the subsidiary’s primary and excess insurers who had agreed in 1997 to pay all defense costs an d be responsible for all damages assessed against the subsidiary arising out of existing and future asbestos claims up to the aggregate limits of their policies. A significant portion of this primary insurance coverage was provided by an insurer that is i nsolvent, and the other primary insurers asserted that the aggregate limits of their policies have been exhausted. The subsidiary challenged the applicability of these limits to the claims being brought against the subsidiary. In response, two of the thr ee carriers entered into separate settlement and release agreements with the subsidiary in 2005 and 2007 for $15,000 and $20,000, respectively. The proceeds of both settlements are restricted and can only be used to pay claims and costs of defense associa ted with the subsidiary’s asbestos litigation. In 2007, the subsidiary and the remaining primary insurance carrier entered into a Claim Handling and Funding Agreement, under which the carrier is paying 27% of defense and indemnity costs incurred by or on behalf of the subsidiary in connection with asbestos bodily injury claims. The agreement continues until terminated and can only be terminated by either party by providing a minimum of two years prior written notice. As of December 31, 2015 , no n otice of termination has been given under this agreement. At the end of the term of the agreement, the subsidiary may choose to again pursue its claim against this insurer regarding the application of the policy limits. The Company believes that, if the coverage issues under the primary policies with the remaining carrier are resolved adversely to the subsidiary and all settlement proceeds were used, the subsidiary may have limited additional coverage from a state guarantee fund established following the insolvency of one of the subsidiary’s primary insurers. Nevertheless, liabilities in respect of claims may exceed the assets and coverage available to the subsidiary. If the subsidiary’s assets and insurance coverage were to be exhausted, claimants of the subsidiary may actively pursue claims against the Company because of the parent-subsidiary relationship. The Company does not believe that such claims would have merit or that the Company would be held to have liability for any unsatisfied obligations of the subsidiary as a result of such claims. After evaluating the nature of the claims filed against the subsidiary and the small number of such claims that have resulted in any payment, the potential availability of additional insurance coverage at the su bsidiary level, the additional availability of the Company’s own insurance and the Company’s strong defenses to claims that it should be held responsible for the subsidiary’s obligations because of the parent-subsidiary relationship, the Company believes i t is not probable that the Company will incur losses. The Company has been successful to date having any claims naming it dismissed during initial proceedings. Since the Company may be in this stage of litigation for some time, it is not possible to esti mate additional losses or range of loss, if any. As initially disclosed in 2010, one of the Company’s subsidiaries may have paid certain value-added-taxes (“VAT”) incorrectly and, in certain cases, may not have collected sufficient VAT from certain custome rs. The VAT rules and regulations at issue are complex, vary among the jurisdictions and can be contradictory, in particular as to how they relate to the subsidiary’s products and to sales between jurisdictions. Since its inception, the subsidiary had be en consistent in its VAT collection and remittance practices and had never been contacted by any tax authority relative to VAT. The subsidiary later determined that for certain products, a portion of the VAT was incorrectly paid and that the total VAT due exceeded the amount originally collected and remitted by the subsidiary. In response, the subsidiary modified its VAT invoicing and payment procedures to eliminate or mitigate future exposure. In 2010, three jurisdictions contacted the subsidiary and, since then, the subsidiary has either participated in an amnesty program or entered into a settlement whereby it paid a reduced portion of the amounts owed in resolution of those jurisdictions’ claims and no related accruals existed as of December 31, 2015 or 2014 . In 2013, an additional jurisdiction issued an assessment against the subsidiary for certain tax years leading to a net charge of $796 , which represented the Company’s best estimate of the amount that may ultimately be paid . The subsidiary filed an appeal of the assessment alleging certain errors by such jurisdiction related to the assessment. During the fourth quarter of 2015, the subsidiary participated in an amnesty program whereby it paid a reduced portion of the amount s owed in resolution of the jurisdictions’ claims, which was materially in line with the Company’s previous estimate. As a result, the Company has no remaining accrual for this or any other related tax assessment at December 31, 2015 . In analyzing the subsidiary’s exposure, it is difficult to estimate both the probability and the amount of any potential liabilities due to a number of factors, including: the decrease in exposure over time due to applicable statutes of limitations and action s taken by the subsidiary, the joint liability of customers and suppliers for a portion of the VAT, the availability of a VAT refund for VAT incorrectly paid through an administrative process, any amounts which may have been or will be paid by customers, a s well as the timing and structure of any tax amnesties or settlements. In addition, interest and penalties on any VAT due can be a multiple of the base tax. The subsidiary may contest any tax assessment administratively and/or judicially for an extended period of time, but may ultimately resolve its disputes through participation in tax amnesty programs, which are a common practice for settling tax disputes in the jurisdictions in question and which have historically occurred on a regular basis, resultin g in significant reductions of interest and penalties. Also, the timing of payments and refunds of VAT may not be contemporaneous, and, if additional VAT is owed, it may not be fully recoverable from customers. As of December 31, 2015 , the Compan y believes there is one potentially impacted jurisdiction remaining, and if the jurisdiction were to initiate audits and issue assessments, the remaining exposure, net of refunds, could be from $0 to $700 , assuming the continued availabilit y of future amnesty programs or settlements to reduce the interest and penalties. If there are future assessments but no such future amnesty programs or settlements, the potential exposure could be higher. The Company is party to other litigation which ma nagement currently believes will not have a material adverse effect on the Company’s results of operations, cash flows or financial condition. The Company leases certain manufacturing and office facilities and equipment under non-cancelable operating lease s with various terms from 1 to 8 years expiring in 2023 . Rent expense for 2015 , 2014 and 2013 was $5,921 , $5,792 , and $5,510 , respectively. The Company’s minimum rental commitments under non-cancelable operating le ases at December 31, 2015 for future years were approximately: 2016 $ 5,291 2017 3,040 2018 779 2019 485 2020 172 2021 and beyond 81

Significant Accounting Polici33

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2015
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation, Policy [Policy Text Block]	All majority-owned subsidiaries are included in the Company’s consolidated financial statements, with appropriate elimination of intercompany balances and transactions.
Consolidation, Variable Interest Entity, Policy [Policy Text Block]	The Financial Accounting Standards Board’s (“FASB’s”) guidance regarding the consolidation of certain Variable Interest Entities (“VIEs”) generally requires that assets, liabili ties and results of the activities of a VIE be consolidated into the financial statements of the enterprise that is considered the primary beneficiary. The consolidated financial statements include the accounts of the Company and all of its subsidiaries i n which a controlling interest is maintained and would include any VIEs if the Company was the primary beneficiary pursuant to the provisions of the applicable guidance.
Equity and Cost Method Investments, Policy [Policy Text Block]	Investments in associated companies (less than majority-owned and in which the Company has significant influence) are accounted for under the equity method. The Company’s share of net income or losses in these investments in associated companies is included in the C onsolidated Statement of Income. The Company periodically reviews these investments for impairments and, if necessary, would adjust these investments to their fair value when a decline in market value or other impairment indicators are deemed to be other than temporary.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Translation of foreign currency: Assets and liabilities of non-U.S. subsidiaries and a ssociated comp anies are translated into U.S. d ollars at the respective rates of exchange prevailing at the end of the year. Income and expense accounts are translated at average exchange rates prevailing during the year. Translation adjustments resulting from this process are recorded directly in equity as accumulated other comprehensive (loss) income (“AOCI”) and will be included as income or expense only upon sale or liquidation of the underlying investment. Generally, all of the Company’s non-U.S. sub sidiaries use their local currency as their functional currency.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and cash equivalents: The Company invests temporary and excess funds in money market securities and financial instruments having maturities typically within 90 days. The Company conside rs all highly liquid investments with original maturities of three months or less to be cash equivalents.
Inventory, Policy [Policy Text Block]	Inventories: Inventories are valued at the lower of cost or market value, and are valued using the first-in, first-out (“FIFO”) method.
Property, Plant and Equipment, Policy [Policy Text Block]	Long-lived assets: Property, plant and equipment are stated at cost. Depreciation is computed using the straight-line method on a n individual asset basis over the following estimated useful lives: building s and improvements, 10 to 45 years; and machinery an d equipment, 1 to 15 years. The carrying value s of long-lived assets are evaluated whenever ch anges in circumstances or current events indicate the carrying amount of such assets may not be recoverable. An estimate of undiscounted cash flows produced by the asset, or the appropriate group of assets, is compared with the carrying value to determine whether an impairment exists. If necessary, the Company recognizes an impairment loss for the difference between the carrying amount of the assets and their estimated fair value. Fair value is based on current and anticipated future cash flows. Upon sa le or other dispositions of long-lived assets, the applicable amounts of asset cost and accumulated depreciation are removed from the accounts and the net amount, less proceeds from disposals, is recorded in the Consolidated Statements of I ncome. Expendit ures for renewals or improvements that increase the estimated useful life or capacity of the assets are capitalized, whereas expenditures for repairs and maintenan ce are expensed when incurred. See Note 12 of Notes to Consolidated Financial Statements.
Internal Use Software, Policy [Policy Text Block]	Capitalized software: The Company capitalizes certain costs in connection with developing or obtaining software for internal use. These costs are amortized over a period of 3 to 5 years once the assets are ready for their intended use.
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill and other intangible assets: The Company records goodwill, definite-lived intangible assets and indefinite-lived intangible assets at fair value at the date of acq uisition. Goodwill and indefinite-lived intangible assets are not amortized, but tested for impairment at least annually. These tests will be performed more frequently if triggering events indicate potential impairment. Definite-lived intangible assets a re amortized over their estimated useful lives, gen erally for periods ranging from 4 to 20 years. The Company continually evaluates the reasonableness of the useful lives of these assets, consistent with the discussion of long-lived asset s, above.
Revenue Recognition Accounting Policy, Gross and Net Revenue Disclosure [Policy Text Block]	Revenue recognition: The Company recognizes revenue in accordance with the terms of the underlying agreements, when title and risk of loss have been transferred, when collectability is reasonably assured, and when pricing is fixed or determinable. For the Company, t his generally occurs when products are shipped to customers or, for consignment-type arrangements, upon usage by the customer and when services are performed. License fee s and royalties are included in other income when recognized in accordance with their agreed-upon terms, when performance obligations are satisfied, when the amount is fixed or determinable, and when collectability is r easonably assured. As part of the Company’s chemical management services, certain third-party product sales to customers are managed by the Company. Where the Company acts as a principal, revenues are recognized on a gross reporting basis at the selling price negotiated with its customers. Where the Company acts as an agent, such revenue is recorded using net reporting as service revenue at the amount of the administrative fee earned by the Company for ordering the goods.
Receivables, Trade and Other Accounts Receivable, Allowance for Doubtful Accounts, Policy [Policy Text Block]	Accounts receivable and allowance for doubtful accounts: Trade accounts receivable subject the Comp any to credit risk. Trade accounts receivable are recorded at the invoiced amount and generally do not bear interest. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses with its existing accounts re ceivable. Reserves for customers filing for bankruptcy protection are generally established at 75-100% of the amount outstanding at the bankruptcy filing date. However, initially establishing a reserve and the amount thereto is dependent on the Company’s evaluation of likely proceeds to be received from the bankruptcy process, which could result in the Company recognizing minimal or no reserve at the date of bankruptcy. Large and/or financially distressed customers are generally reserved for on a specifi c review basis while a general reserve is established for other customers based on historical experience. The Company performs a formal review of its allowance for doubtful accounts quarterly. Account balances are charged off against the allowance when t he Company feels it is probable the receivable will not be recovered. The Company does not have any off-balance-sheet credit exposure related to its customers.
Research and Development Expense, Policy [Policy Text Block]	Research and development costs: Research and development costs are expensed as incurred and are included in selling, general and administrative expenses (“SG&A”) .
Environmental Costs, Policy [Policy Text Block]	Environmental liabilities and expenditures: Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. If there is a range of est imated liability and no amount in that range is considered more probable than another, then the Company records the lowest amount in the range in accordance with generally accepted accounting principles. Accrued liabilities are exclusive of claims against third parties and are not discounted. Environmental costs and remediation costs are capitalized if the costs extend the life, increase the capacity or improve safety or efficiency of the property from the date acquired or constructed, and/or mitigate or p reven t contamination in the future.
Asset Retirement Obligations, Policy [Policy Text Block]	Asset retirement obligations: The Company follows the FASB’s guidance regarding asset retirement obligations, which addresses the accounting and reporting f or obligations associated with the retirement of tangible long-lived assets and the associated retirement costs. Also, the Company follows the FASB’s guidance for conditional asset retirement obligations (“CARO”), which relates to legal obligations to per form an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event that may or may not be within the control of the entity. In accordance with this guidance, the Company records a liability when there is enough information regarding the timing of the CARO to perform a probability-weighted discounted cash flow analysis.
Pension and Other Postretirement Plans, Policy [Policy Text Block]	Pension and other postretirement benefits: The Company maintains various noncontributory retirement plans, the largest of which is in the U.S., covering substantially all of its employees in the U.S. and certa in other countries. The plans of the Company’s subsidiaries in The Netherlands, the United Kingdom (“U.K.”) , Mexico and Sweden are subject to the provisions of FASB’s guidance regarding employers’ accounting for defined benefit pension plans. The plans o f the remaining non-U.S. subsidiaries are, for the most part, either fully insured or integrated with the local governments’ plans and are not subject to the provisions of the guidance. The guidance requires that employers recognize on a prospective basis the funded status of their defined benefit pension and other postretirement plans on their consolidated balance sheet and, also, recognize as a component of other comprehensive income, net of tax, the gains or losses and prior service costs or credits tha t arise during the period but are not recognized as components of net periodic benefit cost. The Company’s U.S. pension plan year ends on November 30 and the measurement date is December 31. The measurement date for the Company’s other postretirement ben efits plan is December 31. The Company’s pension investment policy is designed to ensure that pension assets are invested in a manner consistent with meeting the future benefit obligations of the pension plans and maintaining compliance with various laws and regulations including the Employee Retirement Income Security Act of 1974 (“ERISA”). The Company establishes strategic asset allocation percentage targets and appropriate benchmarks for significant asset classes with the aim of achieving a prudent b alance between return and risk. The Company’s investment horizon is generally long term, and, accordingly, the target asset allocations encompass a long-term perspective of capital markets, expected risk and return and perceived future economic conditions while also considering the profile of plan liabilities. To the extent feasible, the short-term investment portfolio is managed to immunize the short-term obligations, the intermediate portfolio duration is immunized to reduce the risk of volatility in in termediate plan distributions, and the total return portfolio is expected to maximize the long-term real growth of plan assets. The critical investment principles of diversification, assessment of risk and targeting the optimal expected returns for given levels of risk are applied. The Company’s investment guidelines prohibit use of securities such as letter stock and other unregistered securities, commodities or commodity contracts, short sales, margin transactions, private placements (unless specificall y addressed by addendum), or any derivatives, options or futures for the purpose of portfolio leveraging. The target asset allocation is reviewed periodically and is determined based on a long-term projection of capital market outcomes, inflation rates, fixed income yields, returns, volatilities and correlation relationships. The interaction between plan assets and benefit obligations is periodically studied to assist in establishing such strategic asset allocation targets. Asset performance is monitor ed with an overall expectation that plan assets will meet or exceed benchmark performance over rolling five-year periods. The Company’s pension committee, as authorized by the Company’s Board of Directors, has discretion to manage the assets within establ ished asset allocation ranges approved by senior management of the Company.
Comprehensive Income, Policy [Policy Text Block]	Comprehensive income (loss): The Company presents other comprehensive income (loss) in its Statement of Comprehensive Income. The Company follows the FASB’s guidance regarding the disclosure of reclas sifications from AOCI which requires the disclosu re of significant amounts reclassified from each component of AOCI, the related tax amounts and the income statement line items affected by such reclassifications. The Company elected to present the information in its Notes to the Consolidated Financial S tatements.
Income Tax, Policy [Policy Text Block]	Income taxes and uncertain tax positions: The provision for income taxes is determined using the asset and liability approach of accounting for income taxes. Under this approach, de ferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes represents income taxes paid or payable for the current year and the change in d eferred taxes during the year. Deferred taxes result from differences between the financial and tax bases of the Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are re corded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized.
Income Tax Uncertainties, Policy [Policy Text Block]	The FASB’s guidance regarding accounting for uncertainty in income taxes prescribes the recognition threshold and measurement attributes for fina ncial statement recognition and measurement of tax positions taken or expected to be taken on a tax return. The guidance further requires the determination of whether the benefits of tax positions will be more likely than not sustained upon audit based up on the technical merits of the tax position. For tax positions that are determined to be more likely than not sustained upon audit, a company recognizes the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settleme nt in the financial statements. For tax positions that are not determined to be more likely than not sustained upon audit, a company does not recognize any portion of the benefit in the financial statements. Additionally, the Company monitors and adjusts for derecognition , classification, and penalties and interest in interim periods, with appropriate disclosure and transition thereto . A lso , the amount of interest expense and income related to uncertain tax positions is computed by applying the applicabl e statutory rate of interest to the difference between the tax position recognized, including timing differences, and the amount previously taken or expected to be taken in a tax return. The Company’s continuing practice is to recognize interest and/or pe nalties related to income tax matters in income tax expense. Finally, when applicable, t he Company net s its liability for unrecognized tax benefits against deferred tax assets related to net operating losses or other tax credit carryforwards that would ap ply if the uncertain tax position were settled for the presumed amount at the balance sheet date.
Derivatives, Policy [Policy Text Block]	Derivatives: The Company is exposed to the impact of changes in interest rates, foreign currenc y fluctuations, changes in commodity prices and credit risk. The Company is currently not using derivative instruments to mitigate the risks associated with foreign currency fluctuations, changes in commodity prices or credit risk, but has used derivative financial instruments primarily for purposes of hedging exposures to fluctuations in interest rates in the past. When used, the Company recognized all derivatives on its balance sheet at fair value. For derivative instruments designated as cash flow hed ges, the effective portion of any hedge would be reported in AOCI until it was cleared to earnings during the same period in which the hedged item affected earnings.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair value measurements: The Company utilizes the FASB’s guidance regarding fair value measurements, which establishes a common definition for fair value to be applied to guidance requiring use of fair value, establishes a framework for measuring fair value and expands disclosure about such fair value measurements. Specifically, the guidance utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into thr ee broad levels. See Note 22 of Notes to Consolidated Financial Statements. The following is a brief description of those three levels: • Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities. • Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. • Level 3: Unobservable inputs that reflect the reporting entity's own assumptions.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-based compensation: The Company applies the FASB’s guidance regarding share-based payments, which requires the recognition of the fair value of stock-based compensation as a component of expense. The Company has a long-term incentive program (“LTIP”) for key employees which provides for the granting of options to purchase stock at prices not less than its market value on the date of the grant. Most options become exercisable between one and three years after the date of the grant for a period of time determined by the Company, but not to exceed seven years from the date of grant. Restricted stock awards and r estricted s tock u nits (“RSU”) issued under the LTIP program are generally subject to time vesting over a one to five-year period. In ad dition, as part of the Company’s Global Annual Incentive Plan (“GAIP”), nonvested shares may be issued to key employees, which generally vest over a two to five-year period. Based on historical experience, the Company has assumed a forfeiture rate of 13% on its nonvested stock awards. The Company will record additional expense if the actual forfeiture rate is lower than estimated, and will record a recovery of prior expense if the actual forfeiture is higher than estimated.
Earnings Per Share, Policy [Policy Text Block]	Earnings per share: The Company follows the FASB’s guidance regarding the calculation of earnings per share (“EPS”) for nonvested stock awards with rights to non-forfeitable dividends. The guidance requires nonvested stock awards with rights to non-forfeitable dividends to be included as part of the basic weighted average share calculation under the two-class method.
Segment Reporting, Policy [Policy Text Block]	Segments: The Company’s reporting segments are the same as the Company’s operating segments. The Company’s reportable operating segments evidence the structure of the Company’s internal organization, the method by which the Company’s resources are allocated and the manner by which the Company assesse s its performance.
Business Combinations Policy [Policy Text Block]	Business combinations: The Company accounts for business combinations under the acquisition method of accounting. This method requires the recording of acquired assets, including separately identifiable intangible assets, and assumed liabilities at their respective acquisition date estimated fair values. Any excess of the purchase price over the estimated fair value of the identifiable net assets acquired is recorded as goodwill. The determination of the estimated fair value of assets acquired and liabi lities assumed requires significant estimates and assumptions. Based on the assessment of additional information during the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the estimated fair value of assets acquired and liabilities as sumed.
Costs Associated with Exit or Disposal Activities or Restructurings, Policy [Policy Text Block]	Restructuring activities: Restructuring programs consist of employee severance, rationalization of manufacturing or other facilities and other related items. To account for such programs , the Company applies FASB’s guidance regarding exit or disposal cost obligations. This guidance requires that a liability for a cost associated with an exit or disposal activity be recognized when the liability is incurred, is estimable, and payment is probable.
Reclassification, Policy [Policy Text Block]	Reclassifications : Certain information has been reclassified to conform to the current year presentation.
Use of Estimates, Policy [Policy Text Block]	Accounting estimates: The prepa ration of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilitie s and disclosure of contingencies at the date of the fina ncial statements and the reported amounts of net sales and expens es during the reporting period. Actual results c ould differ from such estimates.

Accounting Changes And Error Corrections [Abstract]
Immaterial Error Correction	During the first quarter of 2013, the Company identified errors in Primex’s estimated 2012 financial statements, which primarily related to a reinsurance contract held by Primex. The identified errors resulted in a cumulative $1,038 understatement of the Company’s equity in net income from associated companies for the year ended December 31, 2012. The Company corrected the errors related to Primex in the first quarter of 2013, which had the net effect of increasing equity in net income from associated companies by $1,038 for the three months ended March 31, 2013 and the year ended December 31, 2013. The Company did not believe this adjustment was material to its consolidated financial statements for the year ended December 31, 2012 or to the Company’s results for the year ended December 31, 2013 and, therefore, did not restate any prior period amounts.	During 2015, the Company identified a correction to the presentation of December 31, 2014 summarized financial information. As a result, the Company revised the December 31, 2014 current assets and current liabilities by increasing such amounts by $15,149 each, from previously disclosed amounts. The Company considers such revisions to the prior period to be immaterial.

Income Tax Examination Description	During 2012, the Italian tax authorities initiated a transfer pricing audit of the Company’s Italian subsidiary, Quaker Italia S.r.l., relating to the tax years 2007, 2008, 2009 and 2010.  During the second quarter of 2015, the Italian tax authorities completed an audit of the Company’s Italian subsidiary, Quaker Chemical S.r.l. (formerly NP Coil Dexter Industries, S.r.l.), relating to the tax years 2010, 2011, 2012 and 2013, and proposed adjustments for those years. In the fourth quarter of 2015, the Company paid the tax liability for these proposed adjustments in full. In the fourth quarter of 2015, the Dutch tax authorities assessed the Company’s Dutch subsidiary for additional income taxes related to the 2011 tax year and the Dutch subsidiary filed a protest of the assessment. In January 2016, the French tax authorities gave notice that they were auditing the Company’s French subsidiary. In February 2016, the Italian tax authorities gave notice that they were starting an audit of the 2013 tax year for Quaker Italia S.r.l. As of December 31, 2015, the Company believes it has adequate reserves, where merited, for uncertain tax positions with respect to these audits.

Immaterial Error Correction			During the first quarter of 2013, the Company identified errors in Primex’s estimated 2012 financial statements, which primarily related to a reinsurance contract held by Primex. The identified errors resulted in a cumulative $1,038 understatement of the Company’s equity in net income from associated companies for the year ended December 31, 2012. The Company corrected the errors related to Primex in the first quarter of 2013, which had the net effect of increasing equity in net income from associated companies by $1,038 for the three months ended March 31, 2013 and the year ended December 31, 2013. The Company did not believe this adjustment was material to its consolidated financial statements for the year ended December 31, 2012 or to the Company’s results for the year ended December 31, 2013 and, therefore, did not restate any prior period amounts.	During 2015, the Company identified a correction to the presentation of December 31, 2014 summarized financial information. As a result, the Company revised the December 31, 2014 current assets and current liabilities by increasing such amounts by $15,149 each, from previously disclosed amounts. The Company considers such revisions to the prior period to be immaterial.

Loss Contingency, Settlement Agreement, Terms	In response, two of the three carriers entered into separate settlement and release agreements with the subsidiary in 2005 and 2007 for $15,000 and $20,000, respectively. The proceeds of both settlements are restricted and can only be used to pay claims and costs of defense associated with the subsidiary’s asbestos litigation. In 2007, the subsidiary and the remaining primary insurance carrier entered into a Claim Handling and Funding Agreement, under which the carrier is paying 27% of defense and indemnity costs incurred by or on behalf of the subsidiary in connection with asbestos bodily injury claims. The agreement continues until terminated and can only be terminated by either party by providing a minimum of two years prior written notice. As of December 31, 2015, no notice of termination has been given under this agreement. At the end of the term of the agreement, the subsidiary may choose to again pursue its claim against this insurer regarding the application of the policy limits.
