Overview
Mechanical seal gasket PTFE plate (also known as PTFE plate, PTFE plate, PTFE plate) is made by molding PTFE resin at room temperature, and then sintering and cooling it
Product Details
Mechanical seal gasket PTFE plate
Polytetrafluoroethylene board (also known as PTFE board),TeflonBoard,TeflonThe board is divided into two types: molding and turning. Its products have a wide range of applications and extremely comprehensive performance: high and low temperature resistance (-192 ℃ -260 ℃), corrosion resistance（strong acid、strong base、aqua regiaExcellent characteristics such as weather resistance, high insulation, high lubrication, non adhesion, and non toxicity. Polytetrafluoroethylene (abbreviated as PTFE)TeflonOr [PTFE,F4]), praised as/commonly known as“Plastic KingChineseProduct NameTeflon “Teflon”Teflon, Teflon, Teflon, Teflon, etc.
It is polymerized from tetrafluoroethylenePolymer compounds, itsstructural formulaFor - [- CF2-CF2-] n -, it has excellent propertieschemical stability、Corrosion resistancePolytetrafluoroethylene, abbreviated as PTFE or F4, is one of the corrosion-resistant materials today. "Plastic King" is the common name for polytetrafluoroethylene, which is a corrosion-resistant plastic. It is not corroded by known acids, bases, salts, or oxidants, and even aqua regia is powerless against it, hence the name Plastic King, except for molten metalssodiumandLiquid fluorineExternally, capable of handling everything elsechemicalsWidely used in various applications that require acid and alkali resistanceorganic solventSealing, high lubrication and non stickinesselectrical insulationAnd good anti-aging endurance, excellent temperature resistance (can work at a temperature of+250 ℃ to -180 ℃ for a long time). Polytetrafluoroethylene itself is not toxic to humans, butproduction processOne of the raw materials used inAmmonium perfluorooctanoate(PFOA) is considered to have the potential tocarcinogeniceffect.
Temperature range of -20 to 250 ℃ (-4 to+482 ° F), allowing for sudden cooling and heating, or alternating cold and hot operations.
Pressure -0.1~6.4Mpa (Full vacuum to 64kgf/cm2)
