1000 �C Calcium silicate thermal insulation boards are composed mainly of SiO2, CaO
and a little of fiber . It is
made by pressing and moulding after chemical reaction under high temperature.

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.
