Dexmet chooses PEEK film for industrial filtration

Comments Email

Dexmet Corporation, the US-based maker of expanded metals, foils and polymers, has added Aptiv film from Victrex, the UK-based maker of high performance polyaryletherketones (PEEK) polymers, to its portfolio of PolyGrid expanded plastics.

The PEEK-based film will complement Dexmet’s range of diamond-mesh expanded plastics which are used for critical applications requiring high temperature stability to filter caustic gases or fluids, such as in the semiconductor, chemical processing and petroleum industries. Traditionally Dexmet have manufactured the meshes using PTFE, PFA or ECTFE.

Ken Burtt from Dexmet said: “All of these materials provide excellent temperature and chemical resistance but none match 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.”
