PAPER MINERALS

Engineered Kaolin for High-Performance Coating

Our meticulously processed kaolin is engineered to enhance the aesthetic appeal and functional performance of coated paper and duplex boards, ensuring consistent excellence approved by global mills.

Superior Brightness & Opacity

Engineered to enhance aesthetic appeal and functional performance, our coating grades exhibit high ISO/GE brightness, significantly improving print quality. The fine particle size ensures excellent opacity and optimal coverage, making our minerals functionally approved by leading paper mills worldwide.

Advanced Coating Performance

Optimizing mineral morphology is paramount for technical efficiency in modern paper chemistry. We distinguish our technical kaolin into three performance-critical categories, each engineered to address specific surface requirements and mill cost-optimization goals.

1. High Brightness Coating Clays
2. Standard Brightness Coating Clays
3. Calcined Clays

Engineered for exceptional optical performance and a higher scattering coefficient, these grades allow for reduced usage levels. Optimized abrasion control ensures peak mill efficiency.

Precision-processed for premium brightness and opacity, these grades are essential for top-tier coated papers, providing the print gloss required for luxury substrates.

A robust, cost-efficient workhorse grade that balances runnability and coverage with reliable optical performance, ensuring consistent output for high-volume mill production.
