Calcite Powder

Calcite Powder

Calcite Powder is a natural form of calcium carbonate with extremely high whiteness, purity, and free-flowing in nature. It is widely used in plastics, paints, rubber, and paper industries due to its low oil absorption, high dispersibility, and compatibility with polymers and other organic additives.

Applications

  • Plastic and polymer industry (as a filler)
  • Paints and coatings
  • Rubber industry
  • Paper manufacturing
  • Ceramics and glass

Frequently Asked Questions

200-300 mesh (25-30 microns): Coarse applications like construction materials
400-600 mesh (15-25 microns): Standard industrial applications, paints, plastics
800-1500 mesh (2-15 microns): Fine applications requiring smooth finish and high opacity

Calcite powder improves paint opacity, reduces costs, enhances durability, and provides better coverage. It also helps in controlling viscosity and improving the overall finish quality.

Calcite is pure calcium carbonate (CaCO3), while dolomite contains both calcium and magnesium carbonate. Calcite offers higher brightness and is preferred for applications requiring maximum whiteness.
