Calcium Silicate Board (calsil board)
Non-asbestos micro porous 650-1000°C Calcium silicate Insulation Board is white and hard high temperature thermal insulation material, which has the characteristics of low bulk density, high strength and low thermal conductivity. It can bear high temperature and corrosion. Our Calcium Silicate Insulation products are widely used in industries like heat supply network of city construction, metallurgy, petroleum, chemical, electronics, machinery and glass.
Our Calcium silicate board is an asbestos-free thermal insulation product that can withstand continuous operating temperature from 650℃up to 1100℃. It is light weight, low thermal conductivity, high strength, easy to install, reliable and durable. There are 2 grades available namely 650 &1000 & 1100 which are commonly used as furnace backup insulation in steel, petrochemical, ceramic, cement & glass industry or fire protection in building construction. It not only provides energy saving, also increases production efficiency and gives personnel protection in industrial safety aspect. And in the housing construction Calcium Silicate Board is also used as the ceiling, fireproof and heat insulation materials of wall and sound absorption materials of decoration.
