• Carbon/Graphite-Filled PTFE

PB10000 SERIES

Carbon/Graphite-Filled PTFE

Carbon/Graphite filled PTFE materials have better wear resistance than carbon filled PTFE materials. Carbon/Graphite filled PTFE materials have excellent extrusion resistance and good wear resistance and will work well in both lubricated and non-lubricated environments.

Carbon/Graphite filled PTFE materials are used in static and dynamic applications and used against chromium-plated surface and steel.
