Silicon Carbide Gasket
Edgetech Industries, Advanced Ceramics Division supplies high-quality and competitive price advanced Silicon Carbide (SiC) Gasket.
Silicon Carbide Gasket, SiC Ceramic Gasket
Reaction-bonded Silicon carbide has the advantages of wear resistance, high-temperature resistance, good self-lubrication, high mechanical strength, strong chemical corrosion resistance, and high PV value. It can be used in high-temperature environments up to 1350°C. It is a commonly used friction material in the mechanical sealing industry and is widely used in petroleum, chemical, automotive, pumps, and valves. Edgetech provides customized specifications for Silicon Carbide Gasket.
Pressureless sintered silicon carbide has high thermal conductivity and excellent thermal shock stability, compared with reaction-bonded silicon carbide, it has better wear resistance, high-temperature resistance, and chemical corrosion resistance, especially used in high-demand food, pharmaceutical, and other industries.
