Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Note 1 – Condensed Financial Information The condensed consolidated financial statements included herein are unaudited and have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) for interim financial reporting and the United States Securities and Exchange Commission (“SEC”) regulations. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted p ursuant to such rules and SEC regulations. In the opinion of management, the financial statements reflect all adjustments (consisting only of normal recurring adjustments, except certain material adjustments, as discussed below) which are necessary for a fair statement of the financial position, results of operations and cash flows for the interim periods. The results for the three and nine months ended September 30, 2017 , respectively, are not necessarily indicative of the results to be expected for th e full year. These financial statements should be read in conjunction with the Company’s Annual Report filed on Form 10-K for the year ended December 31, 2016 . During the first quarter of 2017, the Company early adopted an accounting standard upd ate regarding the classification of pension costs. The guidance in this accounting standard update was required to be applied retrospectively, which resulted in a reclassification to the Company’s Condensed Consolidated Statement of Income for the three a nd nine months ended September 30, 2016, respectively. See Note 3 of Notes to Condensed Consolidated Financial Statements. Venezuela’s economy has been considered hyper inflationary under U.S. GAAP since 2010, at which time the Company’s Venezuela equi ty affiliate, Kelko Quaker Chemical, S.A. (“Kelko Venezuela”), changed its functional currency from the bolivar f uerte (“BsF”) to the U.S. d ollar. Accordingly, all gains and losses resulting from the remeasurement of Kelko Venezuela’s monetary assets and liabilities to published exchange rates are required to be recorded directly to the Condensed Con solidated Statements of Income. During the first quarter of 2016, the Venezuela government announced changes to its foreign exchange controls, including elimi nating the CADIVI, SICAD and SIMADI exchange rate mechanisms and replacing them with a dual exchange rate system, which consists of a protected DIPRO exchange rate, with a rate fixed at 10 BsF per U.S. dollars and, also, a floating exchange rate known as t he DICOM. The DIPRO rate is only available for payment of certain imports of essential goods in the food and health sectors while the DICOM governs all other transactions not covered by the DIPRO. In light of these changes to the foreign exchange control s, during the first quarter of 2016 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 investment and other related assets. The Company did not believe it had access to the DIPRO and, therefore, believed the DICOM to be the exchange rate system available to Kelko Venezuela , which resulted in a currency conversion charge of $0.1 million in the first quarter of 2016 . Due to ongoing economic and political instability in Venezuela, the DICOM BsF per U.S dollar exchange rate has continued to devalue during 2017. This resulted in the Company recording a currency conversion charge of less than $0.1 million and $0. 4 million in th e three and nine months ended Se ptember 30, 2017, respectively, to write down the Company’s equity investment to the current DICOM exchange rate. These currency conversion charges were recorded through equity in net income of associated companies in the Company’s Condensed Consolidated Statement of Income for each period, respectively. As of September 30, 2017 , the Company’s equity investment in Kelko Venezuela was $0. 1 million, valued at the current DICOM exchange rate of approximately 3 , 341 BsF per U.S. dollar. 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, revenue is recognized on a gross reporting basis at the selling price negotiated with customers. Where the Company acts as an agent, such revenue is recorded using net reporting of service revenue , at the amount of the administrative fee earned by the Company for ordering the goods. Third-party products transferred under arrangements res ulting in net reporting totaled $11.2 million and $33.0 million for the three and nine months ended September 30, 2017 , respectively. Comparatively, third-party products transferred under arrangements resulting in net reporting totaled $10.7 mi llion and $32.8 million for the three and nine months ended September 30, 2016 , respectively.

Business Combination Separately Recognized Transaction [Abstract]
Business Combination Separately Recognized Transactions Table Text Block	Note 2 – Houghton Combination On April 4, 2017, Quaker entered into a share purchase agreement with Gulf Houghton Lubricants, Ltd. to purchase the entire issued and outstanding share capital of Houghton International, Inc. (“Houghton”) (herein referred to as “the Combination”). The shares will be bought for aggregate purchase consideration consisting of: (i) $172.5 million in cash; (ii) a number of shares of common stock, $1.00 par value per share, of the Company comprising 24.5% of the common stock outstanding upon the closing of the Combination; and (iii) the Company’s assumption of Houghton’s net indebtedness as of the closing of the Combination, which was approximately $690 million at signing . At closing, the total aggregate purchase consid eration is dependent on the Company’s stock price and the level of Houghton’s indebtedness. The Company secured $1.15 billion in commitments from Bank of America Merrill Lynch and Deutsche Bank to fund the Combination and to provide additional liquidity , and has since replaced these commitments with a syndicated bank agreement (“the New Credit Facility”) with a group of lenders for $1.15 billion. The New Credit Facility is contingent upon and will not be effective until the closing of the Combination . T he New Credit Facility currently include s a $400.0 million multicurrency revolver, a $575.0 million USD term loan and a $175.0 million EUR equivalent term loan, each with a five year term from the date the New Credit Facility becomes effective. The maximu m amount available under the New Credit Facility can be increased by $200.0 million at the Company’s option if the lenders agree and the Company satisfies certain conditions. Borrowings under the New Credit Facility will generally bear interest at a base rate or LIBOR rate plus a margin . The Company currently estimates the annual floating rate cost will be in the 3.0% to 3.5% range based on current market interest rates. T he New Credit Facility will be subject to certain financial and other covenants , including co venan ts that the Company’s consolidated net debt to adjusted EBITDA ratio cannot exceed 4.25 to 1 and the Company’s consolidated adjusted EBITDA to interest expense ratio cannot be lower than 3.0 to 1. Both the USD and EUR equivalent term loans w ill have quarterly principal amortization during their respective five year terms, with 5% amortization of the principal balance due in years 1 and 2, 7.5% in year 3, and 10% in years 4 and 5, with the remaining principal amounts due at maturity. Until cl osing, the Company will only incur certain interest costs paid to maintain the banks’ committed capital (“ticking fees”), which began to accrue on September 29, 2017. The ticking fees will bear an interest rate of 0.30% per annum. In addition, the issuan ce of the Company’s shares at closing of the Combination was subject to approval by Quaker’s shareholders under the rules of the New York Stock Exchange , and approval was received at a meeting of the Company’s shareholders during the third quarter of 2017. Also, the Combination is subject to regulatory approval in the United States, Europe, China and Australia. T he Company received regulatory approval from China in July 2017 and from Australia in October 2017 . Depending on the remaining regulatory approv als and other customary terms and conditions set forth in the share purchase agreement, the Company currently estimates closing of the Combination to occur either late in the fourth quarter of 2017 or the first quarter of 2018. The Company incurred costs of $9.7 million and $23. 1 million during the three and nine months ending September 30, 2017, respectively, and $1.2 million during the three and nine months ending September 30, 2016, respectively , for certain legal , environment al, financial, and other advisory and consultant costs related to due diligence, regulatory and shareholder approvals as well as integration planning associated wi th the Combination. As of September 30, 2017 and December 31, 2016, the Company had current liabilities related to the Combination of $11.4 million and $0.5 million, respectively, primarily recorded within other current liabilities on its Condensed Consolidated Balance Sheets. In addition, the Company has made certain reclassifications to prior year disclosures regarding combination-related items to conform with the current period presentation.

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
Description of New Accounting Pronouncements Not yet Adopted [Text Block]	Note 3 – Recently Issued Accounting Standards The Financial Accounting Standards Board ("FASB") issued an accounting standard update in August 2017 to increase transparency of the economics related to risk management activities within the financial statements and enhance transparency and understandability of hedge results. This accounting standard update eliminates the requirement to separately measure and report hedge ineffectiveness and requires the entire change in the fair value of a hedging inst rument to be presented in the same income statement line as the hedged item. The guidance within this accounting standard update is effective for annual and interim periods beginning after December 15, 2018. All transition requirements and elections shou ld be applied to hedging relationships existing on the date of adoption. For cash flow and net investment hedges existing at the date of adoption, the Company should apply a cumulative-effect adjustment related to eliminating the separate measurement of i neffectiveness to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the beginning of the fiscal year that the Company adopts. The amended presentation and disclosure guidance is require d only prospectively . Early adoption is permitted including adoption in any interim period for which financial statements have not been issued or made available for issuance. The Company does not currently use any derivative instruments designated as hedg es, but may choose to in the future . The Company has not early adopted the guidance and will evaluate the potential impact of this guidance on future transactions, as applicable. The FASB issued an accounting standard update in May 2017 to clarif y when changes to the terms or conditions of a share-based payment award must b e accounted for as modifications. This accounting standard update will reduce diversity in practice and result in fewer changes to the terms of an award being accounted for as m odifications. This accounting standard update will allow companies to make certain changes to awards without accounting for them as modifications and an entity is not required to estimate the value of the award immediately before and after the change if t he change doesn’t affect any of the inputs to the model used to value the award. The guidance within this accounting standard update is effective for annual and interim periods beginning after December 15, 2017. The guidance within this accounting standa rd update should be applied prospectively to awards modified on or after the adoption date. Early adoption is permitted including adoption in any interim period for which financial statements have not been issued or made available for issuance. During th e second quarter of 2017, the Company elected to early adopt this guidance with no impact to its financial statements. The FASB issued an accounting standard update in March 2017 to improve the presentation of net periodic pension and postretirement benefi t cost. Defined benefit pension and postretirement benefit costs (“net benefit cost”) comprise several components that reflect different aspects of an employer’s financial arrangements as well as the cost of benefits provided to employees. This accountin g standard update require s that an employer disaggregate the service cost component from the other components of net benefit cost, provide s explicit guidance on how to present the service cost component and the other components of net benefit cost in the income statement and allow s only the service cost component of net benefit cost to be eligible for capitalization. The guidance within this accounting standa rd update should be applied retrospectively for the presentation of the service cost component and the other components of net periodic benefit cost in the income statement and prospectively for the capitalization of the service cost component of net periodic benefit in assets. This accounting standard update is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted as of the beginning of an annual period for which financial statements (interim or annual ) have not been issued or made available for issuance. Du ring the first quarter of 2017, the Company elected to early adopt the guidance within this accounting standard update , including the use of a practical expedient which allows the Company to use amounts previously disclosed in its pension and other postret irement benefits note for the prior period as the estimation basis for applying the required retrospective presentation. Adoption of this guidance resulted in a reclassification to the Company’s Condensed Consolidated Statement of Income for the three and nine months ended September 30, 2016, as previously reported cost of goods sold (“COGS”) were reduced by $0. 1 and $0. 4 million, respectively, and selling, general and administrative expenses (“SG&A”) were reduced by $0. 4 million and $1. 3 million, respectively, with a corresponding increase to other expense, net, of $0.5 million and $1.7 million, respectively. In addition , these required retrospective reclassifications resulted in an immaterial adjustment to previously reported direct ope rating earnings within the Company’s reportable operating segment disclosures for the three and nine months ended September 30, 2016, respectively. See Note 4, Note 7 and Note 8 of Notes to Condensed Consolidated Financial Statements. The FASB issued an a ccounting standard update in January 2017 simplifying the test for goodwill impairment by eliminating the Step 2 computation. The accounting standard update modifies the concept of impairment from the condition that exists when the carrying amount of good will exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. The guidance removes the requirement to determine a goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. The guidance within this accounting standard update should be applied on a prospective basis, and is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. During the third quarter of 2017, in connection with the Company’s 2017 annual goodwill impairment test, the Company elected to early adopt this guidance with no impact to its financial statements. The FASB issued an accounting standard update in January 2017 to clarify t he definition of a business with the objective of adding guidance to assist companies with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments in this accounting standard update pr ovide a more robust framework to use in determining when a set of assets and activities is a business. The guidance within this accounting standard update is effective for annual and interim periods beginning after December 15, 2017. Early adoption is pe rmitted in limited circumstances, and the amendments in this accounting standard update should be applied prospectively, with no disclosures required at transition. The Company does not currently meet the criteria for early application of the amendments a nd therefore has not early adopted the guidance. The Company will evaluate the potential impact of this guidance on future transactions, as applicable. The FASB issued an accounting standard update in November 2016 requiring that the statement of cash f lows explain both the change in the total cash and cash equivalents, and, also, the amounts generally described as restricted cash or restricted cash equivalents. This will require amounts generally described as restricted cash or restricted cash equivale nts be included with cash and cash equivalents when reconciling the beginning and ending amounts shown on the statement of cash flows. The guidance within this accounting standard update is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted and the guidance requires application using a retrospective transition method to each period presented when adopted. While permitted, the Company has not early adopted the guidance and is currently evaluating the ap propriate implementation strategy. Adoption of the guidance will not have an impact on the Company’s earnings or balance sheet but will result in changes to certain disclosures within the statement of cash flows, notably cash flows from investing activiti es. The FASB issued an accounting standard update in August 2016 to standardize how certain transactions are classified in the statement of cash flows. Specific transactions covered by the accounting standard update include debt prepayment or debt extingu ishment costs, settlement of zero-coupon debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate and bank owned life insurance polici es, distributions received from equity method investments and beneficial interest in securitization transactions. The guidance within this accounting standard update is effective for annual and interim periods beginning after December 15, 2017. Early ado ption is permitted, provided that all of the amendments are adopted in the same period. The guidance requires application using a retrospective transition method. While permitted, the Company has not early adopted the guidance and is currently evaluating the appropriate implementation strategy. Adoption of the guidance will not have an impact on the Company’s earnings or balance sheet but may result in certain reclassifications on the statement of cash flows, including reclassifications between cash flows from operating activities, investing activities and financing activities, respectively. The FASB issued an accounting standard update in March 2016 involving several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, use of a forfeitu re rate, and classification on the statement of cash flows. The guidance within this accounting standard update was effective for annual and interim periods beginning after December 15, 2016. When adopted, application of the guidance will vary based on e ach aspect of the update, including adoption under retrospective, modified retrospective or prospective approaches. Early adoption was permitted. During the first quarter of 2017, the Company adopted the guidance within the accounting standard update as required. The impact of adoption for the Company included the elimination of recording the tax effects of deductions in excess of compensation cost through equity as the guidance in this accounting standard update requires all tax effects related to share -based payments to now be recorded through the income statement. The tax effects of awards are required to be treated as discrete items in the interim reporting period in which the stock compensation-related tax benefits occur. In addition, when applying the treasury stock method for computing diluted earnings per share, there are no longer assumed proceeds from the stock compensation-related tax benefits and as a result, there are fewer shares considered to be repurchased in the calculation. This result s in an assumption of more incremental shares being issued upon the exercise of share-based payment awards; therefore, equity awards will have a more dilutive effect on earnings per share. As required, the Company has applied these changes in the guidance prospectively, beginning in the first quarter of 2017. The result of these changes was a tax benefit of $0.6 million and $1. 4 million recorded during the three and nine months ended September 30 , 2017, respectively, and an immaterial number of dilutive s hares added to the Company’s earnings per share calculation for the three and nine months ended September 30 , 2017, respectively. In addition, all tax-related cash flows resulting from share-based payments are now required to be reported as operating acti vities in the statement of cash flows under this new guidance. Either prospective or retrospective transition of this provision was permitted, and the Company has elected to apply the cash flow classification guidance on a prospective basis, consistent wi th the prospective transition for the treatment of excess tax benefits in the income statement. Lastly, the accounting standard update permitted Companies to make an accounting policy election to account for forfeitures as they occur for service condition aspects of certain share-based awards, rather than estimating forfeitures each period. While permitted, the Company has decided not to elect this accounting policy change , and instead has elected to continue utilizing a forfeiture rate assumption. Based on historical experience, the Company has assumed a forfeiture rate of 13% on certain of its nonvested stock awards. See Note 6, Note 9 and Note 10 of Notes to Condensed Consolidated Financial Statements. The FASB issued an accounting standard update in February 2016 regarding the accounting and disclosure for leases. Specifically, the update will require entities that lease assets to recognize the assets and liabilities for the rights and obligations created by those leases on the balance shee t, in most instances. The guidance within this accounting standard update is effective for annual and interim periods beginning after December 15, 2018, and should be applied on a modified retrospective basis for the reporting periods presented. Early ad option is permitted. The Company has not early adopted and is currently evaluating the potential impact of this guidance and an appropriate implementation strategy. The Company has begun its impact assessment, including taking an inventory of its outstan ding leases globally. While the Company’s evaluation of this guidance is in the early stages, the Company currently expects adoption of this guidance to have an impact on its balance sheet. The FASB issued an accounting standard update in May 2014 regardi ng the accounting for and disclosure of revenue recognition. 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 Int ernational Financial Reporting Standards. The guidance was effective for annual and interim periods beginning after December 15, 2016, and allowed for full retrospective adoption of prior period data or a modified retrospective adoption. Early adoption w as 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. Ent ities are permitted to adopt the new revenue standard early but not before the original effective date. During 2016 and 2017 , the FASB issued a series of accounting standard updates to clarify and expand on the implementation guidance, including principal versus agent considerations, identification of performance obligations, licensing, other technical corrections and adding certain practical expedients. The amendments in these 2016 and 2017 updates d id not change the core principle s of the guidance previ ously issued in May 2014. During 2016 , the Company reviewed its historical accounting policies and practices to identify potential differences with the requirements of the new revenue recognition standard, as it relate d to the Company’s contracts and sale s arrangements. As of September 30, 2017, the Company has substantially completed its impact assessment for the implementation of the new revenue recognition guidance. This impact assessment and work performed to date included global and cross functional interviews and questionnaires, sales agreement and other sales document reviews , as well as technical considerations for the Company’s future transactional accounting, financial reporting and disclosure requirements. The Company expects to adopt the guid ance in the first quarter of 201 8 , as required, using a modified retrospective adoption approach applied to those contracts which will not be completed as of December 31, 2017. In addition, the Company will elect to apply certain of the permitted practica l expedients within the revenue recognition guidance, including practical expedients around significant financing components, sales taxes and s hipping and handling activities . The Company has begun preliminary considerations for how the new revenue recog nition guidance may impact Houghton, as it pertains to the potential Combination . The Company anticipates using the remainder of 2017 to finalize its impact assessment and to further develop its considerations for the potential Houghton Combination. Based on information reviewed to date and the impact assessment conclusions reached so far , the Company does not expect the adoption of this revenue recognition guidance to have a material impact on its reported earnings, cash flows, or balance sheet ; however , the Company does expect the adoption to increase the amount and level of disclosures concerning the Company’s net sales.

Commitments And Contingencies Disclosure [Abstract]
Commitments And Contingencies Disclosure [Text Block]	Note 16 – Commitments and Contingencies The Company previously disclosed in its Annual Report filed on Form 10-K for the year ended December 31, 2016 that AC Products, Inc. (“ACP”), a wholly owned subsidiary, has been operating a groundwater treatment system to hydraulically contain groundwater contamination emanating from ACP’s site, the principal contaminant of wh ich is perchloroethylene (“PERC”). As of September 30, 2017 , ACP believes it is close to meeting the conditions for closure of the groundwater treatment system, but continues to operate this system while in discussions with the relevant authorities. As of September 30, 2017 , the Company believes that the range of potential-known liabilities associated with the balance of the ACP water remediation program is approximately $0.1 million to $1.0 million. The low and high ends of the r ange are based on the length of operation of the treatment 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 previousl y disclosed in its Annual Report filed on Form 10-K for the year ended December 31, 2016 that 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 defen dants in numerous lawsuits alleging injury due to exposure to asbestos. During the nine months ended September 30, 2017, there have been no significant changes to the facts or circumstances of this matter previously disclosed, aside from on-going claims and rou tine payments associated with this litigation. 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 approximately $2.2 million (excluding costs of defense). 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 environment al problems of which it is aware. A pproximately $0.2 million was accrued at September 30, 2017 and December 31, 2016 , respectively, to provide for such anticipated future environmental assessments and remediation costs. The Company is party to other litigation which management currently believes will not have a material adverse effect on the Company’s results of operations, cash flows or financial condition.

Business Combination Separately Recognized Transactions [Line Items]
BusinessCombinationSeparatelyRecognizedTransactionsDescription			On April 4, 2017, Quaker entered into a share purchase agreement with Gulf Houghton Lubricants, Ltd. to purchase the entire issued and outstanding share capital of Houghton International, Inc. (“Houghton”) (herein referred to as “the Combination”). The shares will be bought for aggregate purchase consideration consisting of: (i) $172.5 million in cash; (ii) a number of shares of common stock, $1.00 par value per share, of the Company comprising 24.5% of the common stock outstanding upon the closing of the Combination; and (iii) the Company’s assumption of Houghton’s net indebtedness as of the closing of the Combination, which was approximately $690 million at signing. At closing, the total aggregate purchase consideration is dependent on the Company’s stock price and the level of Houghton’s indebtedness. The Company secured $1.15 billion in commitments from Bank of America Merrill Lynch and Deutsche Bank to fund the Combination and to provide additional liquidity, and has since replaced these commitments with a syndicated bank agreement (“the New Credit Facility”) with a group of lenders for $1.15 billion. The New Credit Facility is contingent upon and will not be effective until the closing of the Combination. The New Credit Facility currently includes a $400.0 million multicurrency revolver, a $575.0 million USD term loan and a $175.0 million EUR equivalent term loan, each with a five year term from the date the New Credit Facility becomes effective. The maximum amount available under the New Credit Facility can be increased by $200.0 million at the Company’s option if the lenders agree and the Company satisfies certain conditions. Borrowings under the New Credit Facility will generally bear interest at a base rate or LIBOR rate plus a margin. The Company currently estimates the annual floating rate cost will be in the 3.0% to 3.5% range based on current market interest rates. The New Credit Facility will be subject to certain financial and other covenants, including covenants that the Company’s consolidated net debt to adjusted EBITDA ratio cannot exceed 4.25 to 1 and the Company’s consolidated adjusted EBITDA to interest expense ratio cannot be lower than 3.0 to 1. Both the USD and EUR equivalent term loans will have quarterly principal amortization during their respective five year terms, with 5% amortization of the principal balance due in years 1 and 2, 7.5% in year 3, and 10% in years 4 and 5, with the remaining principal amounts due at maturity. Until closing, the Company will only incur certain interest costs paid to maintain the banks’ committed capital (“ticking fees”), which began to accrue on September 29, 2017. The ticking fees will bear an interest rate of 0.30% per annum. In addition, the issuance of the Company’s shares at closing of the Combination was subject to approval by Quaker’s shareholders under the rules of the New York Stock Exchange, and approval was received at a meeting of the Company’s shareholders during the third quarter of 2017. Also, the Combination is subject to regulatory approval in the United States, Europe, China and Australia. The Company received regulatory approval from China in July 2017 and from Australia in October 2017. Depending on the remaining regulatory approvals and other customary terms and conditions set forth in the share purchase agreement, the Company currently estimates closing of the Combination to occur either late in the fourth quarter of 2017 or the first quarter of 2018.

Accounting Standards Update 2017 07 [Member]
New Accounting Pronouncements Or Change In Accounting Principle [Line Items]
New Accounting Pronouncement Or Change In Accounting Principle Description Of Prior period Information Retrospectively Adjusted	The FASB issued an accounting standard update in March 2017 to improve the presentation of net periodic pension and postretirement benefit cost. Defined benefit pension and postretirement benefit costs (“net benefit cost”) comprise several components that reflect different aspects of an employer’s financial arrangements as well as the cost of benefits provided to employees. This accounting standard update requires that an employer disaggregate the service cost component from the other components of net benefit cost, provides explicit guidance on how to present the service cost component and the other components of net benefit cost in the income statement and allows only the service cost component of net benefit cost to be eligible for capitalization. The guidance within this accounting standard update should be applied retrospectively for the presentation of the service cost component and the other components of net periodic benefit cost in the income statement and prospectively for the capitalization of the service cost component of net periodic benefit in assets. This accounting standard update is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted as of the beginning of an annual period for which financial statements (interim or annual) have not been issued or made available for issuance. During the first quarter of 2017, the Company elected to early adopt the guidance within this accounting standard update, including the use of a practical expedient which allows the Company to use amounts previously disclosed in its pension and other postretirement benefits note for the prior period as the estimation basis for applying the required retrospective presentation. Adoption of this guidance resulted in a reclassification to the Company’s Condensed Consolidated Statement of Income for the three and nine months ended September 30, 2016, as previously reported cost of goods sold (“COGS”) were reduced by $0.1 and $0.4 million, respectively, and selling, general and administrative expenses (“SG&A”) were reduced by $0.4 million and $1.3 million, respectively, with a corresponding increase to other expense, net, of $0.5 million and $1.7 million, respectively.

Effect of Plan Amendment on Net Periodic Benefit Cost		$ 4,000
Defined Benefit Plan Description Of Settlements And Curtailments		During the second quarter of 2017, the Company’s U.S. pension plan offered a cash settlement to its vested terminated participants, which allowed them to receive the value of their pension benefits as a single lump sum payment. As payments from the U.S. pension plan for this cash out offering exceeded the service and interest cost components of the U.S. pension plan expense for 2017, the Company recorded a settlement charge of approximately $1.9 million. This settlement charge represented the immediate recognition into expense of a portion of the unrecognized loss within accumulated other comprehensive loss (“AOCI”) on the balance sheet in proportion to the share of the projected benefit obligation that was settled by these payments.
