PTFE Filters Target High-Purity Chemicals
W. L. Gore & Associates has introduced a new 20 nm-rated polytetraflouroethylene (PTFE) filter available in a high-density polyethylene (HDPE) cartridge. The filter 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.
Featuring PTFE membrane technology that provides high particle retention while maintaining process capacity, Gore's new filters are available in three retention ratings, including 0.1 µm, 30 nm and 20 nm. The 20-nm filter features a 20 nm-rated PTFE membrane in an HDPE cartridge, which enable a drop-in retention upgrade without sacrificing existing system flow.
