Carbonized Fiber packing is braided from shrink-proof oxidized polyacrylonitrile fiber and impregnated with PTFE dispersion containing graphite particles, silicon-oil-free. Compared to traditional carbon fiber packing, it is not brittle, suited for high peripheral speed. It has high strength and good thermal conductivity. PTFE and graphite makes the packing excellent in self-lubrication, thus does no damage to shafts and has long life.

AP2201 can be used in weak acid and alkali or medium containing few grain of solid particles. Application is suitable both dynamic and static seal, mainly used for centrifugal pumps, plunger pumps, mixers and valves.
