Insulation Materials

Mullite Insulating Brick

Mullite Insulation Brick is a kind of quality refractory insulation material for resisting high temperature with features of lightweight, 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, the lining of ceramic high-temperature furnace and so on.
