Calcium Silicate Boards

We supply Calcium Siliate Insulation Board in Classified Temperature from 900 ºC TO 1100 ºC

Calcium silicate insulation board is produced from basic material calcium and silicon and provides excellent service in demanding fire-proof applications. Calcium silicate boards are widely used in pipes and thermal equipments, power station, petrolchemical, foundry industrial as thermal insulation. It is also used as back-up lining for industrial furnaces.
