IFB30 Insulating Fire Brick

CCEFIRE® IFB30 Insulating Fire Brick is a high-refractoriness lightweight mullite-based insulating refractory brick designed for high-temperature industrial furnace systems. The product is manufactured using high-purity refractory clay as the primary raw material, with an optimized material composition that includes a higher alumina content to improve refractoriness and thermal stability.
During production, carefully graded organic pore-forming additives are incorporated into the brick body. These additives burn out completely during the firing process, creating a uniform and controlled porous structure. This engineered structure allows the IFB30 insulating fire brick to maintain a lightweight body while providing good mechanical strength and stable high-temperature performance.

Compared with medium-temperature insulating fire bricks, IFB30 maintains excellent dimensional stability and low thermal conductivity under higher operating temperatures. This helps reduce furnace heat loss and improves the overall thermal efficiency of kilns and industrial heating equipment.

Thanks to its higher refractoriness and stable structural properties, IFB30 insulating fire brick can be used in furnace chamber areas exposed to elevated temperatures. It can also serve as the hot-face insulation layer or as a backup insulation layer behind dense refractory materials in industrial furnace lining systems.
