- Product Features
Improves creep resistance, both at low and high temperatures; Chemically stable (except for strong alkalis and hydrofluoric acid (HF)); Little effect on the electrical properties of PTFE, and improves wear and friction behavior; PTFE Glass filled is very commonly used in valve seat applications. Increased compressive strength and creep resistance of the material allow much greater pressure on the valve seat and as such a much higher rated valve.
