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 Rubber

10–25% by weight as a reinforcing and extending filler.

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