Treated (Coated) Calcium carbonate is the most commonly used filler in Plastics, PVC Cables, and compounding/masterbatch due to its  convenient costs, smoothness, low abrasion, low oil absorption, low moisture, superior brightness, and ease of dispersion with conventional mixing equipment.

Precipitated Calcium Carbonate (PCC) grades, especially if coated with Stearic Acid, are used as fillers in rubber and plastics to improve impact resistance, surface gloss, erosion, shrinkage control etc,.

PCC is commonly used in rigid and flexible PVC and PVC Plastisols. Fine and super fine natural products are also commonly used in PVC as well as in polypropylene and in polyester molding compounds. In rubber, stearate-coated ultrafine PCC is used for its low moisture absorption, good dispersion, and good elastomer-filler contact.
