HCS-23 calcium silicate insulating slab of our company has the advantages of high heat resistant temperature, great adiabatic performance, small bulk density, high specific strength, excellent durability and easy processing for construction. It can be cut and processed by ordinary wood processing machine. The long-term service temperature is 1000℃. The product is noncombustible and has no flame, no smoke and no toxic when exposed to heat and fire.

The calcium silicate insulating slab is widely applied for energy saving and heat preservation in industrial areas referring to glass, steel, cement, petrochemistry, metallurgy, ceramics, electric power plant and electrolytic aluminum. It's often used as the insulation lining of fire resistant construction such as industrial kiln, smelter, drying furnace, boiler, and furnace and heat accumulator. It can also be used as the inwall insulation lining of civil fireplace to achieve energy saving and decreasing the heat loss.
