PTFE combines high heat resistance, chemical resistance, and natural lubricity. It has the lowest coefficient of friction of any solid material, and also one of the lowest thermal expansion rates. In addition, PTFE possesses excellent electrical insulation properties. It does suffer from low tensile and compressive strength. PTFE is widely used in chemical processing equipment, valves, pumps,
insulators, gaskets, and bushings. PTFE can withstand continuous operating temperatures up to 500°F.
