Mullite Insulation Brick is a kind of quality refractory insulation materials for resisting high temperature with features of light weight, low thermal conductivity, thermal insulation and high compression strength in the high temperature furnaces or kilns. Mullite Insulation Bricks are mainly used for the top of hot blast stove, stack and bottom of blast furnace, regenerative chamber of glass melting furnace, lining of ceramic high temperature furnace and so on.
Features of mullite insulation brick:
* Low thermal conductivity and Low heat capacity
* High Purity and low impurity content
* Excellent high temperature strength
* Good thermal shock resistance
* Low expansive conductivity
* Great resistance to acid and alkali erosion
