1000 ºCCalcium silicate thermal insulation boards are composed mainly ofSiO2, CaO and a little of fiber . After chemical reactionunder high temperature, it is made by pressing and moulding.
The boaTest Instrument rdsare mainly used in industrial furnaces of stBuilding Hardware eel, electrolytic aluminium, cement, glass, ceramic and so on for refractory and thermal insulation. The products are also used in petrochemistry, building, firStamping eplace, ventilation duct, etc. for fireproof and thermal insulation.It can be used under 1000ºChigh temperature without deformation, fracture and powdering. It is 100% non-asbestos.Our company is the largest manufactory of 1000 º C calcium silicate thermal insulation boards in China, yearly production up to 70, 000m3. Since 1989 we have begun to produce this kind of boards, which have acquired certificate of ISO 9001 in 2007.
