Tetrafluoroethylene (PTFE) gaskets, also known as PTFE gaskets or PTFE gaskets abroad, are flat gaskets, V-gaskets, piston rings, ball valve gaskets, etc., made from polytetrafluoroethylene rods, tubes, and plates through mechanical machining or cutting. They possess excellent characteristics such as corrosion resistance, aging resistance, and non-conductivity. The pH value of polytetrafluoroethylene ranges from 0 to 14 (except for molten alkali metals and fluorine under high temperature and high pressure). It can maintain good mechanical strength between-100°ºC and 100°ºC.Types And Specifications
