Asbestos packing with PTFE white asbestos fibers from woven and then impregnated by PTFE emulsion. Due to the excellent corrosion resistance of PTFE, PTFE emulsion after impregnation to overcome the porous asbestos, asbestos fibers enhanced chemical stability and density, permeability to prevent leakage, reduce wear and tear under axis in order to extend the service life and reduce the torque in order to reduce energy consumption and enhance the cold resistance of the asbestos fibers (heat-resistant but also a decrease of 260 ℃). Asbestos fibers with matrix material to do to overcome some of the shortcomings of PTFE, is no longer produced the phenomenon of cold flow and creep of a corresponding reduction.
       Applied to petroleum, chemical, electric power, shipbuilding, machinery and other industries in a variety of media pumps, valves, flanges, etc. Sealed.
