regular, hydrous, and calcined grades
AGS Kaolin
AGS Kaolin Product Description
Kaolin is a kind of a silicate mineral with a layered structure. It is widely used in many industrial products: most commonly in paper, ceramics, dry mixtures, insulation materials, wallpaper, and plastics. AGS Kaolin is provided in three main groups of products:
- Ball kaolins
- Hydrous kaolins
- Calcined kaolins
Below you can find technical specifications of selected ball kaolin grades. If you are interested in hydrous or calcined kaolins, please use the contact form below to request more information.
