It is a woven containing graphite fibers made of PTFE packing. For all chemical media pump shaft seal. Packing with a low coefficient of friction so that the stability of long-life, it also has a good tensile strength and high thermal conductivity. Packing with a mother will not be cut down shaft lubrication dry, and can reduce the cost of the replacement bushings. It can be used to seal alkali, solution, water, steam pump, the centrifugal pump, pressure heaters, blenders, mixers and other heavy acids, in addition to acid oxides things (such as aqua regia, fuming nitric acid), etc.
