High Temperature Calcium Silicate Boards Density 220-250kg/m3 Thickness 25mm-100mm

Calcium silicate is mainly made by silicon dioxide and calcium oxide powder with wood fiber as reinforcing material.

It is a new environment-friendly insulation material, non-toxic and no poisonous substance such as asbestos, sulfur and chlorine.
