Overview of PTFE Sheets

- Oct 15, 2018-

Teflon plate (also known as PTFE Board, Teflon board, Teflon plate) sub-molding and turning two kinds, molded plate is made of PTFE resin at room temperature with the molding process, and then by sintering, cooling and made. PTFE turning plate is made of PTFE resin by pressing billet, sintering, spinning and cutting. Its products are widely used, with extremely superior comprehensive performance: high and low temperature resistance ( -192℃-260℃), corrosion resistance (strong acid, alkali, aqua regia, etc.), weather resistance, high insulation, high lubrication, non-adhesion, no toxicity and other excellent characteristics.

PTFE (abbreviated as Teflon or [Ptfe,f4]), by the United States known as the "Plastic King", Chinese product Name "Teflon", "Teflon" (Teflon), "Teflon", "Special Fu Long", "Teflon" and so on. It is made of tetrafluoroethylene by polymerization of polymer, the structure of the simple type of-[-cf2-cf2-]n-, with excellent chemical stability, corrosion resistance (PTFE referred to as PTFE or F4, is one of the world's most corrosion-resistant materials, "plastic King" is known as PTFE, It is the best plastic for corrosion resistance. It is not by the known acid, alkali, salt, oxidizing agent corrosion, is the most powerful aqua Regia also to it helpless, so named Plastic King, in addition to molten metal sodium and liquid fluorine, resistance to all other chemicals, widely used in a variety of needs acid and alkali and organic solvents, sealing, high lubrication non-viscous, electrical insulation and good anti-aging endurance, Excellent temperature resistance (capable of long-term operation at +250℃ to -180℃ temperature).

PTFE it itself is not toxic to humans, but one of the raw materials used in the production process, ammonium PFOA, is thought to be carcinogenic.

Temperature -20~250℃ ( -4~+482°f), allowing for sudden cold or hot or cold alternating operation.

Pressure -0.1~6.4mpa (all negative pressure to 64kgf/cm2) (fully vacuum to 64kgf/cm2) It has solved many problems in the fields of chemical industry, petroleum, pharmacy and so on. PTFE seals, gaskets, gaskets, PTFE seals, sealing washers are selected suspension polymerization PTFE resin molding process.

PTFE is chemically resistant compared to other plastics, and it has been widely used as a sealing material and filler material. Its complete thermal decomposition at around 500 degrees Celsius has four fluorine ethylene, PTFE and PTFE, these products in high temperature decomposition of high corrosive fluorine-containing gas.
