Washed Kaolin has the characteristics of high whiteness, good particle size distribution and good covering ability. Used in paper industry coated paper, coated paper, whiteboard paper, corrugated paper and coating, can improve the whiteness, smoothness, opacity and gloss of the product and other properties. Rubber industry used as a functional filler, can partially replace white carbon black, play a role in strengthening and reducing costs.
