High Strength Calcium Silicate Board 270kg/m³ (1100°C)

High strength calcium silicate board is mainly composed of xonotlite (6CaO·6SiO₂·H₂O), offering excellent thermal resistance and mechanical strength compared with conventional insulation materials.

With higher density and improved structural performance, this product maintains stability even under high temperature conditions. Minimal crystal water loss ensures no structural damage during operation.

It is widely used in industrial furnaces, steel plants, and high-temperature insulation systems requiring higher strength and durability.

Applications

Industrial furnaces

Steel and metallurgy industry

Petrochemical equipment
