PTFE plate (also called PTFE plate, Teflon plate, Teflon plate) is divided into two kinds of molding and turning. The molded plate is made of PTFE resin at room temperature by molding method,
And then made by sintering, cooling. The PTFE turning plate is made of PTFE resin by pressing, sintering and rotary cutting. Its products are widely used and have an extremely superior comprehensive
Performance: high and low temperature resistance (-192 ℃-260 ℃), corrosion resistance (strong acid, strong alkali, aqua regia, etc.), weather resistance, high insulation, high lubrication, non-adhesion, non-toxic and other excellent characteristics.
PTFE sheet is a polymer compound formed by the polymerization of tetrafluoroethylene. Its structure is-[-CF2-CF2-]n-, which has excellent chemical stability and corrosion resistance.
(PTFE referred to as PTFE or F4, is one of the world's most corrosion-resistant materials, "plastic king" is commonly known as PTFE, it is a kind of corrosion resistance of the best plastic
material. It is not known acid, alkali, salt, oxidant corrosion, is the aqua regia also helpless to it, so named plastic king, in addition to molten metal sodium and liquid fluorine, can withstand its
It is all chemicals, widely used in a variety of need to resist acid and alkali and organic solvents, sealing, high lubrication non-stick, electrical insulation and good anti-aging endurance, temperature resistance
Iso (can work for a long time at a temperature of 250 ℃ to -180 ℃). Dankai PTFE itself is not toxic to the human body, but one of the raw materials used in the production process is complete.
Ammonium fluorooctanoate (PFOA) is thought to have a possible carcinogenic effect.

Temperature -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).
It has solved many problems in China's chemical, petroleum, pharmaceutical and other fields. PTFE seals, gaskets, gaskets, PTFE seals, sealing gaskets are
It is made of suspension polymerization polytetrafluoroethylene resin by molding. Compared with other plastics, Dankai PTFE has the characteristics of chemical corrosion resistance, it has been widely used as a
Sealing materials and filling materials. Its complete thermal decomposition products at about 500 degrees Celsius are tetrafluoroethylene, hexafluoropropylene and octafluorocyclobutane, which decompose at high temperatures.
Highly corrosive fluorine-containing gas.
Use of PTFE plate
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. Dankai
Tetrafluoroethylene plate is suitable for -180 ℃ ~ 260 ℃ temperature, mainly used as electrical insulation materials and contact with corrosive medium lining, support slider, rail seals and lubricating material
Material, rich cabinet furniture to use it in light industry, widely used in chemical, pharmaceutical, dye industry containers, storage tanks, reaction tower kettle, large pipeline anti-corrosion lining materials,
Military and other heavy industries; machinery, construction, transportation and bridge sliders, guide rails; printing and dyeing, light industry, textile industry anti-sticking materials, etc.
