GCC significantly boosts the mechanical properties of plastic composites, including tensile strength, rigidity, and heat resistance, ensuring robust and durable end-products.
As a cost-saving alternative to more expensive fillers, GCC helps reduce overall production costs while maintaining high-quality standards.
It contributes to improved opacity and matte finish, partially replacing high-priced optical fillers like titanium dioxide, enhancing aesthetic appeal.
GCC is eco-friendly, non-toxic, and compliant with international environmental regulations, aligning with the sustainability goals of modern manufacturing.
Properly processed GCC dispersed uniformly within the plastic matrix minimizes interfacial defects, enhancing the overall material performance and reliability.
Qualification Certificate
Choose transport tools that have good tightness and corrosion resistance to avoid scattering of calcium carbonate.
Calcium carbonate packaging should be sealed to ensure integrity, avoid damage to the packaging, and moisture, pollution, and other conditions. Calcium carbonate storage should not allow direct sunlight and a high-temperature environment; the best place is a dry, well-ventilated warehouse.
