Product Description
Light Weight Fireproof 650 calcium silicate board

Light Weight Fireproof calcium silicate board is a new type of microporous structure rigid insulation materials, uses silicon oxide, calcium oxide, and the reinforcing fibers as the main raw materials, made through mixing, heating, gelling, molding, autoclaving and drying processes. It is known as the stability in different temperature, asbestos free and maintain high thermal insulation properties even at 650C.

1.Super light weight
2.Low thermal conductivity, 
3.High rupture and compressive strength, 
5.High insulating effect
6.High efficiency
7.Asbestos free


calcium silicate boards are widely used in power plants, petrochemical plants, pipeline systems equipment, as well as heating pipe network system and non-corrosive to stainless steel.
