PTFE gaskets, also called PTFE gaskets or Teflon (Teflon) gaskets, are made of PTFE rods, tubes and plates mechanically turned or cut into flat gaskets, V-shaped gaskets, piston rings, ball valve gaskets, etc. They have good corrosion resistance, aging resistance and non-conductive properties. It has good characteristics such as corrosion resistance, aging resistance and non-conductivity. Polytetrafluoroethylene pH 0-14 (except for molten alkali metals and fluorine at high temperature and pressure). It can have good mechanical strength between -100℃～100℃. PTFE gasket is called PTFE gasket, also called PTFE gasket or Teflon (Teflon) gasket, made of PTFE rods, tubes, plates by mechanical turning or cutting of flat gaskets, V-shaped gaskets, piston rings, ball valve gaskets and so on. In fluid machinery (such as pumps, compressors, mixing kettles, centrifuges, etc.), the most severe operating conditions of the components to be counted on PTFE gaskets.
