Graphite Filled PTFE Tubes White and Black


PTFE tube:OD:1-600mm,Length:300-50 000mm

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 such as teflon 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 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)

Weather resistance

High insulation

High lubrication

Non adhesion

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 .
