Calcium Carbonate
Calcium carbonate (CaCO₃) is a mineral compound used across plastics, paints and coatings, paper, construction materials, and selected pharmaceutical and food-grade applications. It is commonly used as a functional filler and additive in formulation and manufacturing processes where material properties such as opacity, stiffness, and surface characteristics are relevant.
Plastics & Polymers: Used as a functional filler in polymer systems to influence mechanical properties, processing behavior, and material efficiency considerations.
Paints & Coatings: Incorporated as a functional extender to support opacity, brightness, and formulation balance.
Adhesives & Sealants: Applied in formulations where viscosity control, structural behavior, and shrinkage management are relevant.
Paper Industry: Used in paper production and coating systems to influence brightness, opacity, and print-related performance characteristics.
Construction Materials: Included in cement-based systems and construction composites where mineral fillers contribute to structural and performance balance.
Pharmaceuticals & Food Applications: Used in selected pharmaceutical and food applications subject to applicable grade, specification, and regulatory requirements
Features
- Brightness and whiteness characteristics depending on grade
- Controlled particle size distribution
- Suitable for use as filler and extender in formulated systems
- Contributes to stiffness and opacity in formulated systems
- Compatibility with a range of polymer and composite systems
Available Products
Ground Calcium Carbonate (GCC): Derived from mechanically processed natural limestone or marble, GCC is available in a range of particle sizes suited to varied industrial requirements.
Precipitated Calcium Carbonate (PCC): A synthetically produced form with controlled morphology and finer particle distribution, commonly selected for applications requiring more specific performance characteristics.
Coated Calcium Carbonate: Surface-treated grades designed to improve dispersion behavior and interaction within polymer and elastomer systems.
Fine & Ultrafine Grades: Specially processed grades with very small particle sizes for applications requiring specific optical properties and rheological control.
Custom Grades: Specification-driven formulations adjusted according to requirements such as particle size, surface treatment, purity level, and packaging format.
