SSiC (Pressureless Sintered Silicon Carbide) sealing rings are high-performance ceramic components widely used in demanding mechanical seal applications.
Manufactured through an advanced sintering process without external pressure, SSiC rings offer exceptional hardness, chemical stability, and thermal resistance.
Key Features:
Excellent chemical resistance to acids, alkalis, and corrosive fluids
High hardness and wear resistance, ensuring long service life
Superior thermal shock resistance and high-temperature stability (up to 1700°C)
Low friction coefficient, ideal for high-speed and high-pressure sealing environments
High mechanical strength and dimensional stability
Typical Applications:
Mechanical seals in pumps, compressors, and mixers
Sealing systems in petrochemical, pharmaceutical, and food processing industries
Equipment for power generation, chemical processing, and water treatment
Suitable for both stationary and rotating sealing parts
