Precision minerals for high-spec performance
Our Performance Minerals range covers the higher-value, precisely processed kaolin grades in our portfolio — washed, calcined, and spray-dried kaolin — each refined through advanced wet processing and thermal treatment to deliver functional properties that bulk grades cannot match.
These grades are engineered for manufacturers who need dependable whiteness, controlled particle size distribution, and predictable rheological behaviour batch after batch, backed by our in-house laboratory testing and Certificate of Analysis on every shipment.
Refined grades, engineered for function
Washed Kaolin Clay
Hydro-cyclone washed and purified to remove grit, iron, and silica, delivering high whiteness, fine particle distribution, and excellent casting behaviour for ceramics and coatings.
Calcined Kaolin Clay
High-temperature calcination boosts opacity, brightness, and electrical/thermal resistance — ideal for paints, plastics, cable insulation, and specialty coatings.
Spray-Dried Kaolin
Micro-granulated for free-flowing handling, faster dispersion, and dust-free dosing in high-throughput rubber, plastic, and polymer compounding lines.
Functional benefits that matter downstream
