OverviewPolytetrafluorothene, commonly known as “non-stick coating” or “easy-to-clean wok material”; is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene.

PTFE bubble point membrane material is acid and alkali resistant, resistant 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 friction coefficient is extremely low, so it can not only be used for lubrication, but also become an ideal coating for the inner layer of easy-to-clean woks and water pipes.
PTFE bubble point membrane is known as/commonly known as the “King of Plastics”, and its Chinese trade names are “Teflon”, “Teflon” (teflon), “Teflon”, “Teflon”, “Teflon” Dragon” etc.
It is a polymer compound made of tetrafluoroethylene and has excellent chemical stability and corrosion resistance (it is one of the most corrosion-resistant materials in the world today, except for molten metal sodium and liquid fluorine) , can withstand all other chemicals and does not change when boiled in aqua regia. It is widely used in various applications that require resistance to acids, alkalis and organic solvents), sealing, high lubrication and non-stickiness, electrical insulation and good anti-aging endurance and resistance. Excellent temperature resistance (can work for a long time at temperatures from +250°C to -180°C).
Polytetrafluoroethylene itself is not toxic to humans, but perfluorooctanoate (PFOA), one of the raw materials used in the production process of PTFE bubble point membrane, is considered to be potentially carcinogenic.
Temperature -20~250°C (-4~+482°F), allowing sudden cooling and heating, or alternating hot and cold operation.
Pressure -0.1~6.4Mpa (Full vacuum to 64kgf/cm2) (Full vacuum to 64kgf/cm2) The production of PTFE bubble point membrane has solved many problems in my country’s chemical industry, petroleum, pharmaceutical and other fields.
PTFE seals, gaskets, and gaskets. PTFE seals, gaskets, and gaskets are molded from suspension polymerized PTFE resin.
PTFE has the characteristics of chemical resistance and corrosion resistance compared with other plastics. It has been widely used as sealing material and filling material.
PTFE bubble point film is used as engineering plastics and can be made into polytetrafluoroethylene tubes, rods, strips, plates, films, etc.
Generally used in corrosion-resistant pipes, containers, pumps, valves, radars, high-frequency communication equipment, radio equipment, etc. that require high performance.
The dispersion can be used as an insulating impregnation liquid for various materials and as an anti-corrosion coating on the surfaces of metal, glass, and ceramics.
Various PTFE rings, PTFE gaskets, PTFE packing, etc. are widely used in various types of anti-corrosion pipeline flange seals.
In addition, PTFE bubble point film can also be used for spinning, polytetrafluoroethylene fiber – fluoron (foreign trade name is Teflon).
At present, various types of PTFE products have played a decisive role in the national economic fields such as chemical industry, machinery, electronics, electrical appliances, military industry, aerospace, environmental protection and bridges.
The use conditions of PTFE bubble point membrane are in chemical industry, petrochemical, oil refining, chlor-alkali, acid production, phosphate fertilizer, pharmaceuticals, pesticides, chemical fiber, dyeing, coking, gas, organic synthesis, non-ferrous smelting, steel, atomic energy and high-purity product production (such as ion membrane electrolysis), viscous material transportation and operation, food, beverage and other processing and production departments with highly strict hygiene requirements.
