PTFE Rod: Thickness: 5-500 mm Size: 300-3000mm
PTFE plastic 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 packing materials in chemical processing equipment; as electrical insulation for maximum reliability; and in bearings, seals, piston rings and other mechanical applications, especially those require anti-stick characteristics. PTFE plastic has excellent thermal and electrical insulation properties. it has a low coefficient of friction.
Characteristics of PTFE plastic
High and low temperature resistance(-180ºC~+260 ºC)
Corrosion resistance(strong acid, strong alkali and aqua regia, 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.
