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.

Product:
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.
