Product Description
High Thermal Conductivity YSZ Zirconia Ceramic Ring Insulation Rings
In the industrial areas of petrochemical, chemical fiber, fertilizer, atomic energy, aerospace and machinery manufacturing. The higher requirement for mechanical seal should be able to operate under high speed, high pressure, high temperature, low temperature, strong corrosion and solid particles.
Zirconia is a material with superior performance in inorganic non-metallic materials. It is resistant to corrosion, high temperature and wear resistance, and is known for its strong strength and toughness.It makes mechanical seal ring, which can prolong the life of the sealing ring, reduce the number of change, reduce the cost and improve the efficiency.
Properties Sheet:
The Mechanical Seal Ceramics are made of high purity Zirconia ceramics (Zro2) and Alumina Ceramics (Al2O3) material, which have advanced and excellent performances, fabulously popular.
