Description
What is calcium carbonate
Calcium carbonate (CaCO₃) is a widely used functional filler and additive in the rubber and plastic industries due to its cost-effectiveness, versatility, and performance-enhancing properties. It is available in two primary forms: Ground Calcium Carbonate (GCC) and Precipitated Calcium Carbonate (PCC), each offering distinct advantages depending on the application.
Core Features
1. Cost Efficiency & Filler Performance
Volume Extender – Reduces raw material costs by partially replacing more expensive polymers/rubber without sacrificing quality.
High Loading Capacity – Can be incorporated at high percentages (up to 50% in plastics, 30-60% in rubber) while maintaining performance.
Density Modifier – Adjusts product weight (e.g., lightweight plastics or dense rubber parts).
2.Surface & Optical Properties
Whiteness & Brightness – Acts as a white pigment, improving aesthetics in colored rubber and plastic products.
Matte/Smooth Finish – Enhances surface texture in films, sheets, and coatings.
Opacity Improvement – Boosts light-blocking properties in packaging films.
3.Chemical & Processing Advantages
Acid Scavenger – Neutralizes acidic byproducts in PVC processing, improving stability.
Anti-Blocking Agent – Prevents plastic films from sticking together.
Flame Retardant Synergist – Works with other additives to improve fire resistance.

FAQ
What is calcium carbonate (CaCO₃), and why is it used in rubber and plastics?
Calcium carbonate is a naturally occurring mineral (found in limestone, chalk, and marble) processed into fine powders for industrial use. It is widely used in rubber and plastics as a:
Cost-effective filler (reduces material costs).
Reinforcing agent (improves strength, stiffness, and durability).
Processing aid (enhances extrusion, molding, and dispersion).
Surface modifier (improves brightness, opacity, and texture).
