Essential Mineral Filler and Performance Enhancer
Heavy Calcium Carbonate (GCC) is derived from high-purity calcite, limestone, or marble through mechanical crushing, grinding, and classification. Distinguished from precipitated calcium carbonate by its higher density (2.7 g/cm³), irregular particle shape, and broader particle size distribution, it provides unique functional properties in composite materials.
Our advanced milling and air classification technologies ensure precise particle size control (5-45 microns) and consistent brightness for uniform batch performance in automated production lines.
Cost-Effective Filler Applications
As a high-volume, low-cost extender, Heavy Calcium Carbonate Powder reduces consumption of expensive resin polymers while enhancing material properties:
- Improves dimensional stability and reduces shrinkage in plastic compounds
- Enhances thermal conductivity for faster production cycles
- Increases impact resistance in PVC profiles and pipes
- Acts as extender pigment in paints for improved opacity and sheen control
- Adjusts viscosity and improves bond strength in adhesives and sealants
Performance-Enhancing Reinforcing Agent
Beyond filling, our calcium carbonate provides significant mechanical property enhancements:
- Increases tensile strength and abrasion resistance in rubber applications
- Enhances stiffness and heat deflection temperature in plastics
- Improves compressive strength in construction materials
- Contributes to paper bulk, stiffness, and printability
Quality Assurance and Sustainability
Each batch undergoes rigorous quality control for chemical composition, particle size distribution, brightness, and moisture content. Our product is sourced from high-purity ore and offers environmental benefits by reducing petroleum-based polymer consumption.
Packaging Options: 25kg paper bags with inner liners, 1-ton bulk bags (FIBCs), and bulk pneumatic tanker deliveries for high-volume requirements.
