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.
