GB-CK80 kaolin is produced through grind, calcination and classification. The well controlled processes ensure the product have no coarse particles, so the end user can achieve a high Hegman grind. The product also have high brightness, good hiding power and superior dispersibility, and it is widely applied in ceramice, rubber, and plastic.
