PTFE (Polytetrafluoroethene, commonly known as "non-stick coating" or "easy-to-clean wok material"; it is the 1 synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene.

PTFE bubble point membrane material has the characteristics of acid and alkali resistance, resistance to various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, and its coefficient of friction is very low, so it can be used for lubrication, and it has also become an ideal coating for the inner layer of easy-to-clean wok and water pipe.

PTFE bubble point film, known as/commonly known as "plastic king", Chinese trade name "Teflon", "Teflon" (Teflon), "Teflon", "Teflon", "Teflon", "Teflon" and so on. It is a polymer compound formed by the polymerization of tetrafluoroethylene. It has excellent chemical stability and corrosion resistance (it is one of the best materials for corrosion resistance in the world today. In addition to molten metal sodium and liquid fluorine, it can withstand other All chemicals can not change when boiled in king water, widely used in all kinds of need to resist acid and alkali and organic solvents), sealing, high lubrication non-stick, electrical insulation and good anti-aging endurance, excellent temperature resistance (can work at a temperature of 250 ℃ to -180 ℃ for a long time). Polytetrafluoroethylene itself is not toxic to humans, but one of the raw materials used in the production process of PTFE bubble point membrane, perfluorooctanoate (PFOA), is considered to be carcinogenic.

Temperature -20~250 ℃(-4~+482 °F), allowing quenching and quenching, or alternating hot and cold operation.

Pressure -0.1~6.4Mpa (full negative pressure to 64kgf/cm2)(Fullvacuumto64kgf/cm2)

The generation of PTFE bubble point membrane has solved many problems in the fields of chemical industry, petroleum, pharmacy and so on. PTFE seals, gaskets, gaskets. PTFE seals, gaskets, sealing gaskets are made of suspension polymerization PTFE resin molding. Compared with other plastics, PTFE has the characteristics of chemical resistance and corrosion resistance, and it has been widely used as a sealing material and filling material.

PTFE bubble point film is used as engineering plastics, which can be made into PTFE tubes, rods, belts, plates, films, etc. It is generally used in corrosion-resistant pipes, containers, pumps, valves, radar, high-frequency communication equipment, radio equipment and so on. The dispersion liquid can be used as an insulating immersion liquid for various materials and an anti-corrosion layer on the surface of metal, glass and pottery. All kinds of PTFE ring, PTFE gasket, PTFE packing, etc. are widely used in all kinds of anti-corrosion pipeline flange sealing. in addition,

PTFE bubble point membrane can also be used for spinning, PTFE fiber-fluorine fiber (foreign trade name is Teflon).

At present, all kinds of PTFE products have played a pivotal role in the national economy such as chemical industry, machinery, electronics, electrical appliances, military industry, aerospace, environmental protection and bridges.

PTFE bubble point membrane use conditions industry chemical, petrochemical, oil refining, chlor-alkali, acid, phosphate fertilizer, pharmaceutical, pesticide, chemical fiber, dyeing, coking, gas, organic synthesis, nonferrous smelting, iron and steel, atomic energy and high purity products production (such as ion membrane electrolysis), viscous material transportation and operation, health requirements are highly strict food, beverage and other processing and production departments.
