High Strength 1100°C Calcium Silicate Board Density 500kg/m³

Our non-asbestos high strength calcium silicate board is specially designed for high temperature insulation applications up to 1100°C. With a density of 500kg/m³, it offers an excellent balance between strength and thermal insulation performance.

The core material is xonotlite (6CaO·6SiO₂·H₂O), which provides superior thermal stability and structural integrity compared to traditional insulation materials. Even under extreme temperatures, the board maintains its strength with minimal shrinkage.

This product is widely used in industrial furnaces, induction furnaces, petrochemical equipment, power plants, and other high-temperature thermal insulation systems.

It is lightweight, durable, non-toxic, and environmentally friendly, making it an ideal solution for modern energy-saving insulation applications.
