HT Calcium silicate insulation
Description: Non-asbestos EASTM HIGH TEMPERATURE 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),pipe cover, calcium silicate powder, insulation cement, ect.
