Product Description
Insulating Fire Brick , Mullite Lightweight Brick , Mullite Fire Brick:

Mullite lightweight brick is made from natural raw materials, low iron high alumina, mullite crystal structure to phase-based high-quality insulating firebrick. 
Mullite Brick select high purity refractory powders, according to the proportion of products required to join the organic compound filler, vacuum compression molding, high temperature sintered mullite lightweight products.


Energy efficiency, high strength, good thermal shock resistance, low thermal conductivity, resistance to penetration ability, resistance to erosion is an ideal long-life product.


The product can be widely used in metallurgy, petrochemical, machinery, ceramics and other industries, for industrial furnace lining or insulation.
