It can be used under 1000�C high temperature without deformation, fracture and
powdering. It is 100% non-asbestos.

The boards are mainly used in industrial furnaces of steel, electrolytic aluminium, cement,
glass, ceramic and so on for refractory and thermal insulation. The products are also used
in petrochemistry, building, fireplace, ventilation duct, etc. for fireproof and thermal
insulation.

Our company is the largest manufactory of 1000 �C calcium silicate thermal insulation
boards in China, yearly production up to 70, 000 cubic meters. Since 1989 we have begun to
produce this kind of boards, which have acquired certificate of ISO 9001 in 2007.
