Basic introduction of PTFE gasket
Jul 17, 2018

Pure polytetrafluoroethylene gasket is a kind of clean seal. Polytetrafluoroethylene gasket is also called PTFE gasket. It is made of polytetrafluoroethylene resin and sintered by die pressing. It has excellent corrosion resistance and good self. Lubricity and non-blocking properties, it is almost resistant to chemical media, and has the characteristics of wear resistance, pressure resistance and low friction coefficient. Widely used in petroleum, chemical, metallurgy, machinery, food, electric power and other corrosive media pipelines, pumps, valves, flange seals of various types of equipment. Operating temperature: -200 ° C - 260 ° C Operating pressure: 0 - 20.0 Mpa ball valve gasket and other good corrosion resistance, anti-aging and non-conducting characteristics. Polytetrafluoroethylene pH 0 - 14 (melted alkali metal and high temperature, except for fluorine under high pressure). It has good mechanical strength between -100 ° C and 100 ° C. The pressure is 10Mpa.
