PB10000 SERIES

Polymide-Filled PTFE

Polyimide is resistant to higher temperatures than aromatic polyesters. Even in dry environments, polyimide-filled PTFE materials will not abrade mating surfaces.

Polyimide-filled PTFE materials have low wear rates and low coefficient of friction and they are used in seal components for static and dynamic applications where resistance to high pressure and temperature is key.

Polyimide-filled PTFE materials are excellent for dry running compressor rings.
