A calcium silicate insulation board is a non-asbestos insulation product that can withstand continuous working temperatures from 650℃ to 1100℃. It is lightweight, has low thermal conductivity, high strength, is easy to install, reliable and durable. Available in 2 grades, 650 and 1000 and 1100, they are commonly used as a backup insulation for furnaces in the steel, petrochemical, ceramic, cement and glass industries or for fire protection in building construction. It not only saves energy but also increases productivity and provides protection for personnel in industrial safety. In housing construction, calcium silicate insulation board is also used as a fireproof insulation material for ceilings and walls and as a decorative sound-absorbing material.
Thermal shock resistance and stability
Consistently low thermal conductivity
High structural strength at high temperatures
Non-combustible
Electrical insulation properties when dry
Easy to process
Insoluble in water, non-corrosive
The calcium silicate insulation board is easy to install and handle, and its low thermal conductivity makes it ideal for insulation. It is non-toxic and asbestos-free.
The calcium silicate insulation board is widely used in urban heat networks, metallurgy, electronics, machinery, steel, petrochemicals, ferrous and non-ferrous metal casting, aluminum, ceramics, glass and other industries.
