Elkton, MD, USA, February 1, 2012 — W. L. Gore & Associates (Gore) has introduced the world’s first 20 nm-rated polytetraflouroethylene (PTFE) filter that is available in a high density polyethylene (HDPE) cartridge. It is part of a new family of PTFE membrane/HDPE filters optimized for the bulk processing of high-purity chemicals used in the fabrication of semiconductors and flat panel displays (FPDs) where optimum purity is critical. The new GORE® Filters feature the company’s latest advance in PTFE membrane technology to provide the highest particle retention possible while maintaining process capacity.
The new PTFE/HDPE filters are now available in three retention ratings – 0.1 µm, 30 nm and 20 nm. The 20 nm filter is world’s first to feature a 20 nm-rated PTFE membrane in an HDPE cartridge. The advanced PTFE filter membrane features a unique structure to deliver exceptional performance. Compared to conventional filtration media, this new PTFE membrane technology provides a significantly increased open porous area available for fluid flow, and the structural characteristics of the membrane provide a high level of retention.
Combined with the low metal ion and organic extractables of an all-HDPE cartridge, these new 20 nm-rated PTFE/HPDE filter cartridges enable a drop-in retention upgrade without any sacrifice to existing system flow. At a 20 nm retention rating, these filters maintain the high flow rate of a comparable best-in-class competitive 0.05 µm-rated PTFE membrane filter while increasing the retention capacity.
Samples are of the newest GORE® Filters PTFE/HDPE are now available in 0.1 µm, 30 nm and 20 nm retention ratings from W. L. Gore & Associates, Inc. For more information, call 1.800.542.3146 or, outside the U.S., +1.410.506.7516 Or visit www.gore.com/hdpefilters.
