Calcium Silicate Board

High Strength Calcium Silicate Board 300kg/m³ (1100°C)

High strength calcium silicate board is made from xonotlite (6CaO·6SiO₂·H₂O), providing superior thermal resistance and mechanical strength compared with standard insulation materials.

With a density of 300kg/m³, this board offers outstanding load-bearing capacity and structural stability under high temperature conditions. Even when exposed to extreme heat, minimal crystal water loss ensures no structural damage.

It is ideal for heavy-duty industrial insulation applications requiring both high strength and high temperature resistance.

Applications

Industrial furnaces and kilns

Steel and metallurgy industry

Petrochemical equipment

High load-bearing insulation structures
