Industrial Chemicals
Calcium Carbonate Powder
CaCO3
Mineral filler and extender for plastics, paints, paper and building materials, and a soil liming agent.
- Chemical name
- Calcium carbonate
- CAS number
- 471-34-1
- Also known as
- Calcium carbonate, Limestone powder
Product overview
Calcium carbonate powder is a finely ground mineral derived from limestone or calcite. It is chemically stable, white to off-white, and cost-effective as a functional filler.
It is used as a filler and extender in plastics, rubber, paints, coatings, adhesives and paper, in building products such as putties and tile adhesives, and in agriculture to raise soil pH. Particle size and whiteness vary by grade and are confirmed on request.
