Problems solved by technology

[0002] Engine sealing gaskets are mainly used to prevent material leakage, and can be made of metal materials, plastics, fabrics, etc., but more and more rubber materials are used at present. Compared with other rubbers, fluororubber has excellent oil resistance and chemical corrosion resistance. Performance, currently widely used in engine gaskets, but with the improvement of engine performance for a long time, the toughness, high temperature resistance and wear resistance of fluororubber can not meet the demand more and more
