Description
Calcium Silicate (CAS 1344-95-2) is an inorganic mineral compound commercially available under trade names including Calflo E, Vansil W-10, Vansil G, and Vanfre IL-2. It belongs to the salts and minerals category and is distributed across European markets for industrial and regulated applications.
In rubber and plastics compounding, Calcium Silicate functions as a reinforcing filler and processing stabilizer, modifying flow behavior under shear to improve extrusion consistency. In pharmaceutical tablet manufacturing, it acts as a glidant and anti-caking agent, reducing interparticle friction to ensure uniform powder flow through dosing equipment.
Calcium Silicate is supplied in white or cream powder form across multiple grades suited to food, pharmaceutical, and industrial specifications, including FCC and Ph.Eur. compliance where applicable. It falls under REACH registration requirements for European supply. Packaging formats vary by grade and volume, with bulk and intermediate bulk container options typically available from European distributors.
