1000 CALCIUM SILICATE INSULATION BOARD

The main constituents of calcium silicate insulation board is Xonotlite and reinforced galss fibre,no asbestos . It is a kind of high efficient energy-saving material with temperature limited 1000 cent-degree.Characterised by low bulk density,high specific strength, superior heat resistance,outstanding thermal insulation,excellent durability, chemical corrosion resistance, easy to be cut by saw and easy installation, calcium silicate can be widely used for the insulation of industrial kiln.
