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 .
