KAOLIN

Kaolin is an aluminium silicate clay mineral with the common name CHINA CLAY. Traditionally used in ceramics, it is also used as industrial filler in a variety of applications such as adhesives, rubber, paint and laundry soap bars.

We supply locally milled kaolin as well as several imported water-washed kaolins which have lower free silica content.

This is a summary of our grades. Let us know the grade of interest and we will send you the full data sheet and any other information you require.
