Pure tetrafluoroethylene products (abbreviated PTFE, F4, Teflon) are made of polytetrafluoroethylene resin powder, pressed by mold, and then sintered at high temperature. With acid and alkali corrosion resistance, high and low temperature resistance (can work at +250℃ to -180℃ for a long time), resistance to a variety of organic solvents, high lubrication non-viscosity, electrical insulation characteristics are called "plastic king", Chinese transliteration called "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon" and so on. Polytetrafluoroethylene is non-toxic and can reach the food application level, so it is widely used in many fields such as pharmaceutical, chemical, petroleum, and electric power.

Modified filled tetrafluoroethylene products are made of polytetrafluoroethylene resin with a certain amount of filler, such as glass fiber, bronze powder, molybdenum disulfide, graphite, carbon fiber, etc., after high-speed mixing, molded and then sintered at high temperature. It has unique compressibility, recovery, sealing and torque retention. In terms of cold flow and the creep characteristics of the material, it overcomes the shortcomings of traditional PTFE, and at the same time it can hold the bolt load better than traditional PTFE, which improves the durability of the seal and reduces the maintenance of the flange. This improves the environment and saves costs.
