Non-asbestos micropores Calcium Silicate Board is a new –style white and hard insulated material, which has the characteristics of small bulk density, high strength and low thermal conductivity. It can bear high temperature and corrosion, tools can optional cut them.
The basic material of calcium silicate board is silica and calcium powder, its reforced material is natural woody fibre, then adding a small amount of additives as well as a large amount of water, after reasonable ingredients, heat of mixing rubber, molding steam, curing crystallization and drying processes, then produce the new building material.
