Application

1. Non -Asbestos calcium silicate insulation products(650) are recommended as thermal insulations of piping and equipment in power station, steel mill and petrochemical industries as well as othervarious fields. It can also be specified to use in furnace as backing material of refractory bricks.

 

2. Non-Asbestos calcium silicate insulation products(1000): are recommended as thermal insulation in stove, cave, dwelling of steelmill, petrochemical, ceramics, glass, cement industries and power industries as well as other various ancillary heating equipment.

 

3. Calcium silicate board for structure steel fire protection: Decoration for columns, girders as fireproof covering materials.

 

4. High strength calcium silicate fireproof board:Widely used as model boards for glass, high temperature blockers, linings, partitions.
