PTFE has the highest melting point and is capable of continued service at -180-260 C. PTFE is a melt processible resin capable of continued service at 204 C. PTFE products are used as gasket and teflon rods materials in chemical processing equipment; as electrical insulation for maximum reliabillity; and in bearings, seals, piston rings and other mechanical applications, especially those require anti-stick characteristics. PTFE has excellent thermal and electrical insulation properties. it has a low coefficient of friction.
High and low temperature resistance(-180ºC~+260 ºC)
Corrosion resistance(strong acid, strong alkali and aqua regia etc)
Non toxic etc
Widely used in Gasket,Valve packing's,Diaphragms and mechanical seals .
linings of pipes ,valves ,Pumps and vessels .Chemical,Machinery fields .Electrical insulation parts .
