What Is Calcium Carbonate?
Major Industrial Applications
Plastics and Polymer Compounds
Calcium carbonate is used as a functional mineral filler in polypropylene, polyethylene, PVC and other polymer systems. Depending on the formulation, it can help improve rigidity, dimensional stability, surface appearance and production economics.
Paints and Coatings
In paints and coatings, calcium carbonate can contribute to opacity, consistency, surface finish and controlled gloss. The required grade depends on the coating system and desired properties.
Construction Materials
Calcium carbonate is used in dry-mix products, adhesives, sealants, flooring materials, putties and other construction formulations.
Paper and Packaging
Selected calcium carbonate grades are used as fillers or coating pigments to support brightness, opacity and surface quality.
What Determines Calcium Carbonate Quality?
Important parameters include:
- CaCO₃ purity
- Particle-size distribution
- D50 and D97 values
- Whiteness and brightness
- Moisture content
- Oil absorption
- Coating condition
- Consistency between batches
CarboCore supplies selected calcium carbonate grades with controlled specifications, laboratory verification and export-focused packaging options.
