Our unpressed sintered silicon carbide Seal Rings have much Superiorities as below:

The Purity of the material silicon carbide is very high, the Abrasion Resistance , the Resistance to acid and alkali corrosive  have greatly surpassed the corresponding characters of Reaction bonded Silicon Carbide. Super Thermostable, max working temperature 1400 Degree. The geometrical measure is highly precise and the shape torlerance rigid,so that it could be used under most of the extreme working conditions such as Petrochemicals etc.
