PGP 6400.
This kind of packing is made from braiding of PTFE and graphite fibers. Because in this kind of composite material, both PTFE and graphite have good self-lubrication property, so the products have very low friction factor and good self-lubrication too. Owing to good heat conductivity of graphite, working temperature of packing can be increase; hence the working life will be longer. These packing are widely applied to sealing at operating places where contamination is not allowed, for example, for sealing of pumps, valves, flanges in equipment of foodstuff, pharmaceutics, paper-making, petroleum industries.
