Heavy calcium carbonate (CaCO₃) is a critical mineral powder derived from natural limestone or chalk through advanced grinding and classification processes. This multifaceted material plays a pivotal role in numerous industries due to its unique properties and wide range of applications. Storaen (Cangzhou) International Trading Co., a leading supplier of industrial materials, offers high-fine white food-grade and industrial-grade heavy calcium carbonate tailored to meet diverse industrial needs.
Heavy calcium carbonate is available in two primary grades: food-grade and industrial-grade. Both grades are widely used as fillers in coatings, plastics, and other materials. They enhance dimensional stability, hardness, and scratch resistance in coatings while improving stiffness and reducing shrinkage in plastics. Light calcium carbonate, often used interchangeably with heavy calcium carbonate, offers similar benefits but with a finer particle size distribution, making it ideal for high-filling applications requiring a smooth finish.

Heavy calcium carbonate is extensively used in coatings to improve dimensional stability, hardness, and scratch resistance. Its high filling capacity ensures that coated surfaces maintain their integrity under various conditions. For example, food-grade calcium carbonate is ideal for applications where safety and hygiene are paramount, such as in food packaging and pharmaceutical coatings.
In plastics, heavy calcium carbonate enhances stiffness and reduces shrinkage during the manufacturing process. This not only lowers production costs but also improves the mechanical properties of the final product. The industrial-grade variant is particularly popular in the production of polyethylene and polypropylene, where it acts as a cost-effective filler without compromising quality.
Beyond coatings and plastics, heavy calcium carbonate is used in paper manufacturing to improve opacity and brightness, in rubber to enhance tensile strength, and in construction materials for its thermal insulation properties. Its versatility makes it a cornerstone in multiple industries.
