Better, Cheaper, Faster, Champ sealing always keep these three promises to our clients. Our goal is to build first class SIC sealing ring products in China and we have passion for it.
Our SIC or SSIC products are - Excellent wear resistance
- Excellent corrosion resistance
- Longer duration under high temperature (1200~1500ºC)
- Over 92 Rockwell of hardness.
- Low coefficient of thermal expansion
Reaction Bonded Silicon Carbide, the RB SiC is cost efficient metrial which provides outstanding wear resistance and good chemical resistance.Sintered Silicon Carbide, the SSiC: the absence of free silicon ion makes SSiC has the best effort to resist aggressive chemically fluids, and ideal performance under high temperatures.Graphite-Loaded Silicon Carbide(SSIC+C) - this is a composite of silicon carbide and free graphite. Graphite is added to RB SiC (RB SiC + C) or SSiC (SSiC + C) to improve tribological performance by enhanced lubricity.
