Calcium silicate board is made of high grade siliceous and calcareous materials with the mixture of natural fiber reinforced substance. It is a brand new architectural and industrial board with excellent performances.

Features:

1.Fireproof:  It is flame resistant to combustion at 800 and remains flameless at1200 . non-flammability: National Standards GB8624 Grade A

2.Humidity Resistance:  The board still keeps Intact after being soaked in water for one month , the phenomenon of swelling and out of shape will Not happen. It will Not disintegrate when Immersed in water or exposed to freeze/thaw cycles for prolonged periods of time.

3. High Strength : the strongest one among the inorganic thermal insulation materials with the similar density

4. Heat Insulation: lower thermal conductivity than other hard mass thermal insulation material

5. Pressure tolerance, and acid resistance.
