Calcium Silicate Board
硅酸钙板
Calcium silicate consists of SiO2, CaO and reinforcing fiber. Made through stirring, heating, gelling, forming, pipe hardening and drying processes. Light bulk weight, low thermal conductivity and high bending and compressive strength. Used in petroleum, electric power, building partition wall, curtain wall, roof and building envelope thermal insulation.
