Calcined Kaolin
Calcined Kaolin is a refined mineral produced by heating carefully selected kaolin clay at controlled temperatures. This thermal treatment removes chemically bound moisture, modifies the mineral structure, and improves important functional properties. The resulting material offers good brightness, opacity, hardness, chemical stability, and reliable performance across demanding industrial formulations.
Its fine particles help improve coverage, surface finish, dimensional stability, electrical resistance, and durability. In paints and coatings, Calcined Kaolin can enhance opacity, whiteness, scrub resistance, and controlled gloss. In plastics and rubber, it functions as a reinforcing mineral filler that supports strength, stiffness, and processing consistency. The appropriate grade should be selected according to particle size, brightness, oil absorption, residue, chemical composition, and application requirements.
Key Benefits:
- High brightness and whiteness
- Improved opacity and coverage
- Excellent chemical stability
- Good electrical insulatione
- Enhanced strength and durability
- Consistent particle distribution
- Reliable processing performance
