Product Description

Product Description

SSIC ceramic ring

silicon carbide seal ring (SiC seal ring) is a high-performance ceramic sealing component engineered for extreme industrial conditions. Manufactured via pressureless/reaction sintering process, it features exceptional hardness, wear resistance, and chemical stability, making it the ideal choice for mechanical seal faces in pumps, compressors, and other rotating equipment.

Silicon carbide ring

Extreme Hardness & Wear Resistance: Mohs hardness ~9.2, second only to diamond, ensuring minimal wear in abrasive and dry-running conditions.

Superb Chemical Corrosion Resistance: Inert to most acids, alkalis, and organic solvents, perfect for harsh chemical environments.

Excellent Thermal Stability: Operates stably at >1000°C, with high thermal conductivity and low thermal expansion, preventing deformation.

Low Friction Coefficient: Provides smooth, energy-efficient operation and extends service life.

High Mechanical Strength: Outstanding compressive and bending strength for high-pressure applications.
