Product description

 

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 .

Application

Mechanical Seal

Chemical anticorrosion, Chemical Process Vessel Seal

Machine tool guideways lubrication

Bridge  construction support slider 

Pipe sealing in high temperature and high corrosive condition
