Factory Supply Anti-corrosion Pure PTFE Envelope Sealing Gasket for Electrical Applications
PTFE (polytetrafluoroethylene gasket) is also called PTFE gasket abroad. Flat gasket, V-shaped gasket, piston ring and ball valve gasket made of PTFE rod, tube and plate by mechanical turning or cutting have good characteristics of corrosion resistance, aging resistance and non-conductivity. The pH value of PTFE is 0-14 (except for molten alkali metals and fluorine at high temperature and high pressure). It has good mechanical strength between - 180ºC and 200ºC. Pressure 10 Mpa. PTFE gasket is a kind of clean sealing product, which does not pollute any substances it touches, and can be widely used in food, medicine and other industries.
PTFE (ptfe coated cushion) performance characteristics:
1. Combining the different characteristics of lining core material and the corrosion resistance of PTFE
2. Low friction coefficient, not easy to bond, easy to install and disassemble
3. Clean product, can be used in machine and flange sealing parts
4. Good compression resilience performance

Etched PTFE
Due to the low surface activity and non-stickiness of PTFE, it is necessary to modify the surface of PTFE to improve its surface activity. Chemical corrosion modification can improve the surface activity of PTFE by treating it with certain chemical reagents. Usually etched PTFE can bond well with rubber, metal, and other materials after proper treatment.
