Low price high density 25mm 650 waterproof fireproof insulation calcium silicate board
Calcium silicate boards are a new type of micro-porous structure rigid insulation materials, uses silicon oxide, calcium oxide, and the reinforcing fibers as its main raw materials, made through mixing, heating, gelling, molding, autoclaving and drying processes. It is known as the stability in different temperature, asbestos-free and high thermal insulation properties at 650C.
calcium silicate board characteristics:
1. Super light weight
2. Low thermal conductivity,
3. High rupture and compressive strength,
4. Waterproof
5. High insulating effect
6. High efficiency
7. Asbestos free
calcium silicate board application:
calcium silicate board price is widely used in power plants, petrochemical plants, pipeline systems equipment, as well as heating pipe network system and non-corrosive to stainless steel.
