Silicon Carbide Seal Rings

Silicon carbide is the ideal sealing materical. It has good corrosion resistance. Higher mechanical internsity, excellent resisting wearability And high temperature, good self-lubricity and making-group, low fricition factor, good heat-conduction and so on.
Especially sintered silicon carbide, it is very good suit for the hard working condition.
The silicon carbide, as the high-temperature structural material, is widely used in the petroleum, the chemical industy, Machinery, war industry, shiping, spaceflight, the automobile and other fields. It is widely applied to friction material of mechanical seals, especially friction material of slush pump.
