Product Description

Semicorex silicon carbide Mechanical Seal Parts offer tribological performance under high load, including pressure, sliding speed and temperature. Components manufactured from silicon carbide provide long-lasting service due to its high resistance to wear, resistance to corrosion in aggressive media and thermal shock resistance with low distortion under thermal loads.
Our Mechanical Seal Parts can be customized for your unique application. The specialists will assist you with initial design and development, and our extensive and well-equipped manufacturing facilities allow us to quickly scale-up to full production.

The difference between SSiC and RBSiC:

1. Sintering process is different. RBSiC is to infiltrate free Si into silicon carbide at a low temperature, SSiC is formed by natural shrinkage at 2100 degrees.

2. SSiC have smoother surface, higher density and higher strength, for some sealings with more strict surface requirements, SSiC will be better.

3. Different used time under different PH and temperature, SSiC is longer than RBSiC
