1000 ºCCalcium silicate thermal insulation slabs are composed mainly ofSiO2and CaO, 100% non-asbestos.
It is made by pressing after chemical reactionunder high temperature.The slabsdsare mainly used in industriaDiamond Tools l furnaces of steel, aluminium, cement, glass, ceramic and so on for refractory and thermal insulation. The products are also used in petrochemistry, building, wall, ventilation duct, fireproof door, etc for fireproof or thermal insulation.It can be used under 1000ºChigh temperature without deformation, fracture aHand Tools nd powdering
