High Brighthness Low Ferrous Washed Kaolin Clay Powder for Paper GRPY-1
As a result of its pore structure, this series produces make the coating having excellent bulk density and printing adaptability. They can improve the smoothness and brightness of the paper as its sheet structure. Used in papermaking, they can instead the titanium dioxide or other high cost filling pigments to reduce production cost.
Product Advantages
