Calcium Silicates Wollastonite Superfine Powder

Calcium Silicate UNISILC CSW 4000 is a natural mineral which consists of a combination of calcium, silicon and oxygen elements, has the chemical compound Ca2SiO4 and also sometimes in the form of 2CaO.SiO2 or CaSiO3 compounds which are usually referred to as wollastonite compounds.

Judging from its physical properties, Calcium Silicate is in the form of a white or whitish cream colored powder which has the characteristics of being soft, easy to flow, has a low bulk density, has quite high-water absorption capacity, has quite high resistance to heat, so with its characteristics Like this, calcium silicate is widely used as a filler material for products for thermal insulation applications, fire protection and acoustic insulation.
