Driven by the need to provide solutions for increasingly harsh environments in filtration for the industrial market, Dexmet Corp., a manufacturer of precision expanded metals, foils and polymers, added a high performance polymer to its PolyGrid portfolio. Dexmet chose APTIV® film made with VICTREX® PEEK polymer to add to their portfolio where an expansion procedure using specifically designed proprietary equipment and processes are used to produce diamond configured, open area mesh products. Critical applications requiring high temperature stability to filter caustic gases or fluids, such as in the semiconductor, chemical processing, and petroleum/gas industries, have traditionally used polymers such as polytetrafluoroethylene (PTFE), perfluoroalkoxy copolymer (PFA), and ethylene chlorotrifluoroethylene copolymer (ECTFE). All of these materials provide excellent temperature and chemical resistance but none matches the mechanical strength provided by the expanded APTIV films. With the continual increase in demands on filter performance, VICTREX PEEK-based PolyGrid is the solution to meet the critical performance challenges.
