                         Polypore Expands Asian Presence
- --------------------------------------------------------------------------------

CHARLOTTE, N.C. - June 16, 2005 - Polypore, Inc. announces that it will further
expand its presence and market capabilities in Asia, reflecting Polypore's
commitment to support its customers and the industries in which it participates.
In order to better accommodate customer growth and related demand for both
lead-acid and lithium battery separators in the greater Asian market, Polypore
will transfer certain assets from Europe and the United States to its facilities
in Thailand and China. This opportunity for production realignment in its Energy
Storage business demonstrates the Company's continual focus on driving
improvement in all areas of its business.

This capacity realignment plan for its Energy Storage business includes the
closure of the company's facility in Feistritz, Austria, the downsizing of its
Norderstedt, Germany facility and the relocation of certain assets from these
two plants to the Company's facilities in Prachinburi, Thailand. Additionally,
certain finishing equipment from the Company's facility in Charlotte, North
Carolina will be relocated to its facility in Shanghai, China, while maintaining
the Charlotte-based finishing operation in support of its customer base in North
America and Europe.

"The focus at Polypore is on continual improvement in all facets of our
business. Through these efforts, we have increased our capacity in Europe and
North America. As a result, we are able to relocate some of our production
assets to the high growth regions of Asia and enhance our ability to serve this
vital region, without sacrificing our ability to support customers in Europe and
other regions around the World. We believe this move will better position the
company to benefit from the growth in Asia by keeping capacity and inventory
close to the customer and allowing us to be more responsive to their needs,"
commented Frank Nasisi, President and Chief Executive Officer of Polypore, Inc.

On June 15th, the company completed a technical amendment to its credit
agreement to provide certain definitional changes to accommodate the asset
relocations envisioned in this project. Details of the amendment are available
on form 8-K which will be filed shortly with the Securities and Exchange
Commission.
