The mullite heat insulation brick series products are made of natural high-quality high-alumina low-iron raw materials, and the high-quality heat-insulating refractory bricks are mainly composed of mullite crystal phase. The products have high compressive strength, good thermal shock resistance and thermal conductivity. Low, anti-penetration ability, erosion resistance, etc., can be widely used in metallurgy, petrochemical, machinery, ceramics and other industries, to make industrial furnace lining or insulation layer, is an ideal product for longevity energy saving and efficiency. Wood powder and polystyrene beads can be added according to user requirements to produce polylight mullite heat-insulating bricks.
