Calcium silicate board for thermal insulation
Calcium silicate board is made of xonotlite and reinforced glass fiber, resistant to high temperatures up to 1100 ºC. It features excellent heat insulation, low bulk density, high strength, and superior durability. It is widely used for industrial furnace insulation.
Commonly known as microporous calcium silicate, this white, hard insulation material is characterized by its light density, low thermal conductivity, and corrosion resistance. Its ability to be easily sawed and cut makes it ideal for pipes, walls, and roofs in electric power, metallurgy, petrochemical, construction, and shipbuilding sectors.
Product Characteristics:
Application Fields:
It is widely utilized for thermal insulation and fire prevention in electric power, metallurgy, and petrochemical industries. High-density versions are specifically developed for the non-ferrous industry, used in the casting and molding of molten aluminum, and as clamping fixtures in the glass industry.
