Polytetrafluoroethylene sheet (also called tetrafluoroethylene sheet, Teflon sheet, Teflon sheet) is divided into two types: molded and turned.

Teflon sheet (also called teflon sheet, Teflon sheet, Teflon sheet) is divided into two types: molded and turned. Molded sheet is made of Teflon resin by molding at room temperature, then sintered and cooled. Teflon turned sheet is made of Teflon resin by pressing, sintering and rotary cutting. Its products are widely used and have 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-adhesive, non-toxic and other excellent characteristics. Polytetrafluoroethylene (abbreviated as Teflon or [PTFE,F4]), known as "King of Plastics", Chinese trade names "Teflon", "Teflon" (teflon), "Teflon", "Teflon", "Teflon", "Teflon" and so on.

It is a polymer compound made of tetrafluoroethylene by polymerization, its structural short formula is -[-CF2-CF2-]n-, with excellent chemical stability, corrosion resistance (PTFE or F4 for short, is one of the corrosion-resistant materials in the world today, "plastic king" is the common name of polytetrafluoroethylene, it is a kind of plastic with good corrosion resistance. It is a plastic with good corrosion resistance. It is not known acid, alkali, salt, oxidant corrosion, is the powerful aqua regia also can not do anything to it, so named plastic king, in addition to molten metal sodium and liquid fluorine, can resist all other chemicals, widely used in a variety of need to resist acid and organic solvents, sealing, high lubrication non-stick, electrical insulation and good anti-aging resistance, excellent temperature resistance (can be in +250 ℃ to -180 ℃ under the temperature long-term work). PTFE itself is not toxic to humans, but one of the raw materials used in the production process, ammonium perfluorooctanoate (PFOA), is considered potentially carcinogenic.
