Mechanical Ring Parts Ceramic Seal Rings with Heat Resistant

High resistance ceramic sealing ring by high technology advanced ceramics and refractory temperature: 1750 ℃.High temperature ceramic seal ring are made of the corresponding ceramics (normal type, high purity type, high aluminum type, zirconium type) as raw materials through isostatic pressure, precision processing, sintering and other processes.
 
High resistance ceramic seal ring is widely used in heat insulation gasket;Kiln masonry lining and expansion joint sealing;High temperature pipe heat insulation;Non-ferrous metal melting groove, groove pad;Observation hole of industrial kiln;Kiln door brick and burner brick;Insulation gaskets for electrical equipment connection;High temperature filtration material;It can replace asbestos products.
 
Characteristics:
low thermal conductivity, low thermal capacity, excellent chemical stability, excellent non-flammability, excellent thermal stability, excellent thermal shock resistance, excellent sound absorption.
