Treated calcium carbonate

Properties of treated calcium carbonate

Color: Pure white.
Appearance: Very fine powder (micron or nano).
Surface: Coated with a thin, oily (organic) film that prevents clumping and increases dispersibility.
Density: Approximately 2.7 g/cm³ as untreated.
Soluble: Insoluble in water, soluble in acids, but treatment makes it less hygroscopic and more stable.

Improved compatibility with polymers such as:
- PP (Polypropylene)
- PE (Polyethylene)
- PVC (Polyvinyl chloride)
- and others.
Improved mechanical properties of plastics:
- Increased rigidity.
- Improved scratch resistance.
- Improved plastic flow during injection or extrusion.
Easier distribution and mixing.
- With the coating, it integrates homogeneously into the mixture.
Lower moisture absorption.
- This increases the lifespan of the industrial product.

It is natural calcium carbonate (GCC) that is ground and then surface-treated, often using stearic acid or other materials.
The aim of the treatment is to improve compatibility with polymers and plastics and increase performance in industrial applications.

- Plastics industry: A key sector for increasing rigidity and reducing costs while maintaining properties.
- Paints and coatings: Provides smoothness, prevents caking, and improves durability.
- Rubber: Improves abrasion resistance and mechanical properties.
- Pipe, wire, and cable manufacturing: To reduce costs and improve performance.
