PTFE GASKET

Teflon, a synthetic fluoropolymer with excellent dielectric properties and a low coefficient of friction, is the DuPont brand name for polytetrafluoroethylene (PTFE). Teflon gaskets provide excellent thermal insulation and resist corrosive chemicals.
PTFE gasket material combines excellent dielectric properties with a very low coefficient of friction and an ability to service a wide range of operating temperatures, from -400°F to 500°F. The real strength of PTFE gasket material is that is among the most chemically resistant materials known.
Polytetrafluoroethylene (PTFE), (The Chemours Company's trademark of Teflon®) is a thermoplastic member of the fluoropolymer family of plastics. PTFE has a low coefficient of friction, excellent insulating properties, and is chemically inert to most substances
