Calcium Silicate is a versatile, high-performance functional additive produced as a fine white powder with varying bulk densities. It is widely recognized for its superior anti-caking properties and ability to improve flow characteristics in powdered mixtures.

Featuring exceptional water absorption capacity, this material acts as a highly efficient drying agent and carrier for liquids, ensuring product stability in humid environments. Its porous structure allows it to absorb significantly more than its own weight in oil or water while maintaining a free-flowing state.

In industrial applications, it serves as a robust reinforcing filler and pigment extender, contributing to the durability and thermal insulation of end products. It is chemically inert, resistant to high temperatures, and available in Food Grade (E552) and technical specifications.

Calcium silicate

  • Food Processing: Acts as a premium anti-caking agent in powdered foods, table salts, spices, and baking powders to prevent clumping and ensure smooth dispensing.
  • Thermal Insulation: Manufactured into calcium silicate boards and blocks to provide high-temperature insulation for industrial piping, furnaces, and fireproofing applications.
  • Paints & Coatings: Functions as a functional filler and pigment extender to improve brightness, scrub resistance, and control sheen in interior and exterior paints.
  • Pharmaceuticals: Used as an excipient and tablet disintegrant, aiding in the compression of active ingredients while managing moisture content.

Calcium Silicate is generally considered safe for industrial and food use but is classified as a nuisance dust. Inhalation of high concentrations may cause mechanical respiratory irritation. Personnel should ensure adequate ventilation and wear dust masks or respirators alongside safety goggles to prevent eye irritation during handling and transfer operations.
