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.
