PTFE (polytetrafluoroethylene)

Polytetrafluoroethylene (PTFE) shows a remarkable chemical resistance and it is insoluble in all known solvents. It is attacked only by molten alkali metals and by fluorine at high temperatures. PTFE is a soft, low friction fluoropolymer with outstanding chemical resistance and weathering resistance. PTFE is a strong, waxy, tough, non-flammable synthetic resin produced by the polymerization of terafluoroethylene. PTFE is stable at temperatures up to 500ºF and it is often used in high temperature environments.

PTFE also has excellent electrical insulating properties and is distinguished by its slippery surface, high melting point, and resistance to attack by almost all chemicals. These properties have made it familiar to consumers as the coating on nonstick cookware; it is also fabricated into industrial products, including bearings, pipe liners, and parts for valves and pumps.

PTFE is a self-lubricating material that provides a low friction coefficient and excellent chemical resistance. PTFE offers the lowest coefficient of friction of any known material and operates up to 500°F with superior insulating properties.
