• Coated calcium carbonate powder is a specially treated form of ground calcium carbonate (GCC) where each particle is coated with a surface modifier, typically stearic acid.
• This coating improves the compatibility of calcium carbonate with non-polar polymers and enhances dispersion within plastic and rubber matrices.
• Coated Calcium Carbonate is produced by surface coating the regular calcium carbonate slurry with stearic acid.

• Improved Dispersion: Surface coating reduces agglomeration, ensuring even distribution in polymers.

• Enhanced Hydrophobicity: The coating minimizes moisture absorption, making it ideal for moisture-sensitive applications.

• Better Compatibility: Offers superior interaction with polyolefins like PE, PP, and PVC.

• Increased Process Efficiency: It reduces energy consumption during extrusion or injection molding thanks to its smoother flow properties.

• Boosts Final Product Performance: It enhances mechanical properties, surface finish, and dimensional stability in end-use products, leading to better overall quality.
• Moreover, it offers good opacity and brightness, which are essential in visual and functional applications.
• It also provides increased thermal stability, making it suitable for high-temperature processing.
• As a result, it remains a cost-effective choice for manufacturers seeking performance and value.
• Improved Flowability: It aids in processing methods such as extrusion and injection molding, allowing for smoother operations.
• In addition, it is widely used as a filler in polypropylene to achieve a good balance of rigidity and impact strength.

Applications of Powder-Coated Calcium Carbonate:

• • Plastic industries: It improves processing and product strength.

  • Rubber and elastomers: It increases tensile strength and flexibility, making them more durable.

  • Coatings and adhesives: It enhances consistency, reduces costs, and increases durability.

  • Wire and cable insulation: Used for its thermal and mechanical stability.

  • PVC pipes and profiles: It reinforces the structure and improves surface finish.
