Calcium silicate board is take high grade siliceous and calcareous materials, reinforcing fiber as the main raw materials, by a certain percentage mixing, made through a series of processes. Calcium silicate board is an asbestos-free thermal insulation product, which is fireproof, thermal insulation, mothproof and preventing mildew.
Calcium silicate board is light weight, low thermal conductivity, high strength, easy to install, high temperature resistance, corrosion resistance, reliable and durable. it is widely used in electricity, metallurgy, petrochemical, construction, shipbuilding and other areas of equipment, piping, wall and roof insulation and fire insulation.
