Calcium silicate insulation:
Description: Non-asbestos calcium silicate heat-insulating products are nonpoisonous, tasteless, nondusty, and have the adcantages of light specific gravity, high strength, small thermal conducttivity and convenience in laying. So that , they are largery used in power, chemical, oil, gas, ship, steel and textile industries for the thermal insulatin of heating power pipe and installations.Calcium silicate can be made into calcium silicate board(slab), arc board, block, preformed pipe section, skin, calcium silicate powder, insulation cement, ect. Base materials of our calcium silicate insulation: Non-combustible, inorganic, hydrous calcium silicate (asbestos free) with non-asbestos fiberous reinforcement, composite silicate skin........ Comply with ASTM C 533, Type I.
