Ultra High Strength Calcium Silicate Board 400kg/m³ (1100°C)

Ultra high strength calcium silicate board is manufactured from xonotlite (6CaO·6SiO₂·H₂O), offering exceptional thermal resistance and superior mechanical performance.

With an ultra-high density of 400kg/m³, this board provides outstanding load-bearing capacity and structural stability under extreme high-temperature conditions. Even at elevated temperatures, minimal crystal water loss ensures long-term durability without structural damage.

It is specially designed for heavy-duty industrial applications requiring maximum strength and high temperature resistance.
