Teflon plate

PTFE plate is also called PTFE plate, Teflon plate and Teflon plate. It is a polymer compound formed by polymerization of tetrafluoroethylene. Its structure is-[-CF2-CF2-]n-, which has excellent chemical stability and corrosion resistance (PTFE or F4 for short, is one of the most corrosion-resistant materials in the world today. "Plastic King" is commonly known as PTFE, which is the 1 kind of plastic with the best corrosion resistance.

It has solved many problems in China's chemical, petroleum, pharmaceutical and other fields. PTFE seals, gaskets, gaskets. 3. PTFE seals and sealing gaskets are made of suspension polymerization PTFE resin molding. Compared with other plastics, PTFE has the characteristics of chemical resistance, it has been widely used as a sealing material and filling material.

Its complete thermal decomposition products at about 500 degrees Celsius are tetrafluoroethylene, hexafluoropropylene and octafluorocyclobutane, which decompose highly corrosive fluorine-containing gases at high temperatures.

Teflon plate

Teflon plate is not corroded by known acids, alkalis, salts and oxidants, and even the most powerful aqua regia is helpless to it, so it is named plastic king, which can withstand all other chemicals except molten metal sodium and liquid fluorine, 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 250 ℃ to -180 ℃ temperature for a long time). Polytetrafluoroethylene itself is not toxic to humans, but one of the raw materials used in the production process, ammonium perfluorooctanoate (PFOA), is considered to be carcinogenic.

The temperature is -20~250 ℃(-4~482 °F), allowing quenching and quenching, or alternating hot and cold operation;

Pressure -0.1~6.4Mpa (full vacuum to 64kgf/cm2);

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.

Tetrafluoroethylene plate is suitable for temperature of -180 ℃ ~ 250 ℃, and is mainly used as electrical insulation material and lining, supporting slide block, track seal and lubricating material in contact with corrosive medium. It is used in light industry and is widely used in anti-corrosion lining material of chemical industry, medicine, dye industry containers, storage tanks, reaction towers and large pipelines. Aviation, military and other heavy industrial fields; Machinery, construction, transportation bridge sliders, guide rails; anti-sticking materials for printing and dyeing, light industry and textile industry, etc.
