Products News

PTFE Membrane Filters in HDPE CartridgesPTFE Membrane Filters in HDPE CartridgesW. 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. www.gore.com

The company must offer cleaning, restoration, repairing, and protective services.
Not only is this an easier option, but they have the proper equipment
to acquire the job done correct. Fire damage insurance varies
from company to help company, and state to state.

The dehumidifier is used after the water has been pumped out.
