Two types of PTFE rods are available. The rods of diameter 4-9mm are extruded from dispersion PTFE resin, those of diameter 10-50mm are plunger-extruded from suspension PTFE and that of diameter above 50mm die-pressed. Pressed rod, extruded rod, die-pressed rod, diameter 10 mm-50mm
PTFE has a wide range of practicable temperature from -180+260 and a wax-like surface to which anything hardly sticks.PTFE has the lowest coefficieng of friction of all known solid materials.It has the best electrical properties of all plastics.
Application
The electrical insulation used under various kinds of frequency, the seal liner of various kinds of corrosivity medium, Antisticking materials, lubriation material.
