GCC vs Modified Calcium Carbonate
Compare GCC and modified calcium carbonate for plastic filler, PVC, coating and other industrial applications.
Published 2026-06-01
Ground Calcium Carbonate, usually called GCC, is natural calcium carbonate powder produced by grinding mineral resources. Modified calcium carbonate is surface-treated calcium carbonate, often used when dispersion and compatibility are important in plastic systems.
For many industrial buyers, GCC can be suitable for general filler use in plastics, coating, rubber and building materials. Modified calcium carbonate may be more suitable for filler masterbatch, PVC compounds and other applications where processing performance matters.
The decision should not be based only on price. Buyers should compare particle size, D97, whiteness, oil absorption, moisture, surface treatment and application performance.
