Application in Ground Calcium Carbonate
Ground calcium carbonate is widely used as a filler and coating pigment in industries such as paper, paint, plastics, rubber, and pharmaceuticals, enhancing product performance and cost-effectiveness.
Plastics and Rubber Industry:
Ground calcium carbonate (GCC) is a key filler in the plastics and rubber industries, enhancing mechanical properties like strength, impact resistance, and dimensional stability of products. Its fine particle size and uniform distribution enable efficient blending with polymers, improving processability and performance while reducing material costs as a cost-effective extender.
Paper and Pulp Industry:
In the paper and pulp industry, ground calcium carbonate (GCC) serves as both a coating and filling agent, enhancing paper opacity, brightness, and printability for superior visual appeal and print quality. GCC acts as a cost-effective filler, reducing pulp fiber consumption while maintaining paper strength, smoothness, surface properties, and ink receptivity.
Paints and Coatings:
Ground calcium carbonate (GCC) is vital in paints and coatings as both an extender and functional additive, enhancing coverage, hiding power, and durability. Its controlled particle size distribution improves rheological properties and formulation stability, while enhancing surface smoothness, texture, and finish in painted applications.
Adhesives and Sealants:
Ground calcium carbonate (GCC) is integral to adhesives and sealants, enhancing adhesion, cohesion, and flexibility. It improves bond strength and integrity, ensuring durable adhesion. GCC also contributes to rheological properties, viscosity control, and workability, enhancing performance and usability in various adhesive and sealant applications.
Construction Materials:
Ground calcium carbonate (GCC) is employed in construction materials like concrete, mortars, and stuccos as a filler and extender, enhancing workability, strength, and durability. Its fine particle size and uniform distribution improve flow characteristics and cohesiveness in construction mixtures, ensuring enhanced performance and structural integrity.
Pharmaceuticals and Dietary Supplements:
Ground calcium carbonate (GCC) is used in the pharmaceutical and dietary supplement industries as a calcium source, promoting bone health and overall well-being in oral supplements. Its high purity, controlled particle size, and chemical stability ensure suitability for various pharmaceutical formulations, including tablets, capsules, and powders.
