vThe fundamental raw material of this product is high–quality alumina bauxite. Polystyrene microspheres lightening method is adopted in the producing process.
vThe products is high compression strength, good thermal shock stability, low heat conductivity, long-term stable performance in high temperature, etc..
vThe product is widely used for various high-temperature kilns in the field of vIt can be used as the lining or heat insulating layer because it can contact the fire directly. Till now, it is the most ideal heat insulating refractory materials that has good applicability in industry.
