PTFE gasket also known as Teflon gaskets,It is sintering from after Used mold suppress PTFE resin, Or used PTFE rods, tubes, plates by mechanical turning or by cutting. The gasket has excellent corrosion resistance and good self-lubrication, non-adhesive, It is resistant to almost all chemical media. Used in petroleum, chemical, metallurgical, mechanical, electrical and other corrosive media pipeline, pump, valve flange seal all types of equipment. Pure PTFE gasket is also a clean sealing products, will not come into contact with the formation of any contaminated material, can be widely used in food, medicine and industry. At the same time as insulating materials are widely used in the electronics industry. Improved PTFE Gasket uniformly adds filling material as glass fiber, carbon fiber, and graphite powder to the traditional pure PTFE Gasket. Comparing with the pure PTFE Gasket, it has a better compressive strength, wearing resistance, good thermal conductivity, no cold flow, and low thermal expansion, etc. Different Improved PTFE Gasket can satisfy different needs.
