silicon carbide seal ring has the advantages of excellent corrosion resistance, high coefficient of heat conductivity, self-lubricity, small expansion and so on.

 

silicon carbide seal ring can be widely used in the petroleum, chemical, machinery building , metallurgical industry and motors industries. The frictional factor of combination of silicon carbide and carbon graphite is the least.

Material advantage: the usage life of our all material is better than the silicon carbide.

The price of MG1 is similar with silicon carbide, but the transverse rupture strength is stronger, not easier to break in the working.
