Features of thread seal PTFE tape raw material

Application performances:
Polytetrafluorothylene (F4, PTFE) possesses a series of excellent application performances, which are: heat resistant -long period of using under the temperature of 200~260°C; low temperature resistance - still soft at the temperature below 100°C; corrosion resistant - resistant to aqua regia and all organic solvents; weather resistance – the best aging life in plastic; high lubrication - with the smallest friction coefficient (0.04) in plastic; non-stick – has the smallest surface tension without adhering to any substance in the solid material; nonhazardous – possesses physiologically inertness; and excellent electrical properties, which is an ideal C-grade insulation material. PTFE material, widely used in national defense, atomic energy, petroleum, radio, electrical machinery, chemical industry and other important sectors.

PTFE rod, tube, plate, turning sheet, PTFE tape, etc..

Mechanical properties:
It has a small coefficient of friction, only 1/5 of polyethylene, which is an important feature of perfluorocarbon surface. As well the intermolecular forces are extreme low in Fluorine - carbon chain, so PTFE has the feature of non-stick.

Temperature resistance:
Polytetrafluoroethylene maintains the excellent mechanical properties in a wide temperature range of 196~260°C, one of the characteristics of the perfluorocarbon polymer is not brittle at low temperature.
