China Plastics Teflon PTFE Gasket Manufacture Teflon PTFE Tube Pipe for Washer Expaned Teflon PTFE S

PTFE Tube

PTFE tube:OD:2-500mm,Length:300-50 000mm

PTFE has the highest melting point and is capableWatch Box of continued service at -180-260 C. PTFE is a melt processible resin capable of continued service at 204 C. PTFE products such asteflon gaskets are used as gasket and packing 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 electricMass Transfer and Separation Equipment al insulation properties. it has a low coefficient of friction.
