teflon It is a polymer compound polymerized from tetrafluoroethylene, which has excellent chemical stability, corrosion resistance (except molten metal sodium and liquid fluoride, it can resist all other chemicals, and does not change when boiled in aqua regia, and is widely used in various working conditions requiring acid and alkali resistance and organic solvents), sealing, high lubrication, non adhesion, electrical insulation and good aging resistance Large temperature resistance span (can work for a long time under the temperature of+250 ℃ to - 180 ℃).

Why? PTFE gasket What about being liked?

gather Tetrafluoroethylene gasket No adhesion, polytetrafluoroethylene has small surface tension in solid materials, and does not adhere to any substance. Polytetrafluoro Vinyl gasket Low temperature resistance, good mechanical toughness; The elongation of 5% can be maintained even when the temperature drops to - 196 ° C. It is suitable for sealing parts where temperature and pressure change violently, and is a static sealing element at flange connections such as pipes, valves, pump heat exchangers, towers, manholes, handholes, etc.

PTFE gasket is corrosion resistant, and it is inert to most chemicals and solvents, and resistant to strong acid, strong alkaline water and various organic solvents. This kind of gasket has good compression springback function, multiple seals and certain self tightening function, which can eliminate the influence of pressure, temperature change and mechanical vibration.
