KAOLIN
Kaolin
Kaolin, also known as china clay, is a versatile industrial mineral valued for its whiteness, fine particle characteristics, and functional properties. Depending on its grade and processing, it is used across ceramics, paints, coatings, paper, construction materials, and other industries.
Our Kaolin Products:
Hydrous Kaolin
Hydrous Kaolin is a naturally occurring hydrated clay mineral used in applications that require suitable whiteness, particle characteristics, and formulation performance.
Applications: Ceramics, paints and coatings, paper, and other industrial formulations, depending on grade specifications.
Metakaolin
Metakaolin is produced by the controlled thermal treatment of kaolin. It is commonly used as a supplementary cementitious material and in specialised construction formulations, where it can contribute to strength development and improved material performance.
Applications: Concrete, cement-based products, mortar, and specialised construction materials.
Calcined Kaolin
Calcined Kaolin is obtained through the controlled heating of kaolin to modify its physical and functional properties. It is used in industrial applications that require specific levels of whiteness, opacity, and performance.
Applications: Paints and coatings, ceramics, plastics, rubber, and other suitable industrial applications.
