Modified Filled PTFE Gaskets

PTFE filled gaskets are used as sealing materials. Because of its high corrosion resistance, stable physical properties, high temperature resistance, it has achieved good sealing performance and has wide applications in petroleum, chemical, pharmaceutical, electric power and steel industries. Suitable media include almost all chemical components such as water, oil, acid solution, and alkali solution....

Product Description

PTFE modified gasket is made from PTFE suspension resin with proper fillers such as glass fiber, glass microsphere, graphite, barium sulfate, carbon fiber, molybdenum disulfide, polyphenyl, argil etc. in process of molding or skiving sheet.Added a certain amount of filler, and the compression resistance and high temperature resistance will be greatly improved. It is especially suitable for using as the transmission sealing parts under the condition of - 180 ℃ ~ + 260 ℃ temperature range .
