lightweight insulating fire brick Thermal Insulating mullite Brick

    Product Description Product Description Product Characteristics   Low Thermal Conductivity It has good insulation effect and can thin the thickness of furnace wall. Low thermal capacity Less heat storage, it has good usage effect in intermittent furnace. Good thermal shock resistance and high temperature strength It can prolong the service life of kilns and prevent dirty slag to drop down. Precise dimension It can keep uniform gaps between each brick, speed up the building, guarantee the integrated high strength of the masonry. Low impurity Lower iron and alkali content, it has high resistance to reduce atmosphere corrosion at high temperature. Specification Specification
