Pure PTFE gasket: PTFE gasket Also called PTFE gasket or Teflon (Teflon or Teflon ）The gasket is made of Polytetrafluoroethylene rod The plate is milled or pressed into flat gasket, V-shaped gasket, engine piston and gate valve by mechanical equipment seal ring It has excellent characteristics of corrosion resistance, aging resistance and conductivity.

teflon PH value 0-14 (except molten alkaline earth metal and dispersed fluorine). It can have good impact toughness between - 100 ℃ and 100 ℃. Note: When the temperature is less than - 185 ℃. gather Tetrafluoroethylene gasket It can become brittle.

Pure PTFE Vinyl gasket It is a clean and sealed commodity, and will not cause environmental pollution to all the chemicals it touches. It can be widely used in food, medicine and various industries in highly corrosive occasions.

Modification PTFE gasket (Also known as filled PTFE gasket): The modified filled PTFE gasket shall be made by adding a certain amount of filler materials, such as glass fiber, quartz stone, barium sulfate, high-purity graphite, carbon fiber materials, etc., into the polytetrafluoroethylene epoxy resin. It shall be formed by rubber and plastic products after rapid mixing, and then be sintered at high temperature.

It has excellent expansibility, recovery and sealing performance. Its unique characteristics show tightness and torque maintenance.

In terms of internal cooling and stress relaxation characteristics of raw materials, it solves the defects of traditional PTFE. At the same time, it can maintain bolt preload better than traditional PTFE, which not only optimizes the continuity of sealing, but also reduces the daily maintenance of flange.

The advantages of filling modified PTFE gasket: low friction index, better bonding strength, and improved wear resistance; The application of PTFE has greatly exceeded that of traditional PTFE, which can optimize the natural environment and save costs.

It is generally applicable to chemical plants, machinery and equipment, paper industry, food industry, ultra-low temperature liquid gas, pharmaceutical industry, etc., as well as the sealing field for non polluting environment.
