Surface‑treated (commonly with fatty acids or stearates) to create a hydrophobic shell that reduces agglomeration, improves wetting in polymers, and enhances dispersion. This leads to better flow, smoother surface finish, and improved mechanical integration in PVC, PE, and other hydrophobic matrices.
Coated Calcium Carbonate (Surface‑treated, usually with stearic acid)
- Plastics & PVC Compounding – Improves dispersion in polymer matrices, reduces agglomeration, and enhances surface finish.
- Rubber & Sealants – Provides better flow and compatibility, leading to smoother processing and improved mechanical properties.
- Paints & Coatings – Enhances gloss and smoothness by improving wetting and dispersion in hydrophobic systems.
- Construction Materials – Used where improved workability and surface finish are required.
