Project Description

Calcium Silicate （Ca2O4Si）

Calcium silicate is produced by hard silicalite hydrate and reinforced fibers,100% asbestos free . With the max service temperature of 1050℃,calcium silicate board is a kind of high efficient energy-saving material.

Calcium silicate board have the advantages of low bulk density,low thermal conductivity, good thermal stability,high strength,long durability, excellent corrosion resistance, and good processing performance.

Calcium silicate board and parts are mainly applied to core board of fireproof door, non-ferrous metals smelting,insulation board for kiln and furnace.
