Overview

Ground Calcium Carbonate in PVC Manufacturing

GCC is compounded into PVC formulations as a cost-effective filler that maintains impact strength and processability. Fine particle size grades disperse evenly through the polymer matrix, supporting smooth extrusion and a consistent surface finish.

Prime Carbonate supplies Ground Calcium Carbonate to PVC manufacturers as part of our broader PVC industry supply program, alongside other mineral grades suited to this sector.

Where It's Used

Ground Calcium Carbonate Applications Within PVC

PVC pipes and fittings

Window and door profiles

Vinyl flooring compounds

Cable conduit

Rigid PVC sheets

How It's Used

How Ground Calcium Carbonate Is Incorporated

Ground Calcium Carbonate is typically pre-blended into the resin, binder, or pulp system using high-shear mixers or twin-screw extruders, ensuring the fine mineral particles disperse evenly throughout the base material before further processing.

How Much Is Used

Typical Dosage in PVC

5–15% by weight in rigid PVC compounds.

Actual loading rates depend on your specific formulation and performance targets. Our technical team can recommend a starting point based on your current process.
