This large family of semicrystalline materials is widely known for its chemical inertness, high temperature resistance, and extremely low friction. These materials also exhibit incredible dielectric properties and temperature insulation abilities.

PTFE (Teflon) is the most chemically inert plastic known with an operating temperature of up to 500 degrees F. Its extremely low friction surface, excellent thermal properties, and electrical insulation characteristics make this material a very popular choice for a wide variety of applications. Common uses include: seals, valve seats, bearings, gaskets, packing, insulators, and high heat components.
