These products are made by combining PTFE with graphite.

Because this kind of composite material, PTFE and graghite have good self-lubrication property, so the products have very low friction factor and good self-lubrication property too. Thus, axles of machinery will nt be scratched and the cost for changing axles sleeves will be decreased to a great extent. Owing to good heat conductivity of graphite, woring temperature of packings can be increased, hence the working life will be longer.Furthermore, thay almost suit to all of chemical media.

These packings are widely applied to sealing at operating places where contamination is not permitted, for example, for sealing of pumps, valves, flanges in equipment of foofsuff, pharmacetical, wine-making, petroleum, chemical, power, paper making, printing and dyeing industries.
