Category: Spare Part
Product Style Number & Name:
SP1001 Reaction bonded silicone carbide (RSIC)
SP1002 Pressureless sintered silicone carbide (SSIC)
SP1003 Silicone carbide + carbon (SiC+C)
Silicone carbide is an ideal sealing material. It has good resistance to corrosion, wear and high temperature, high mechanical strength, good self-lubricity and heat conductivity, low friction factor, and easy combination property. The pressureless sintered silicone carbide can especially suit hard working conditions.
Silicone carbide products include: SiC rings, bushings and bearings etc.
As an excellent high-temperature structural material, the silicone carbide has been widely used in the industries of petroleum, chemical, machinery, military, shipping, spaceflight, and automobile etc. It is also widely applied as friction material in the mechanical seals, especially for slush pump.
