SX-98C is of low abrasion value which result in reducing paper machine loss and printing equipment loss and lowering cost. It can be used as pigment and filler in coated paper industry due to its fine particle size, high whiteness and excellent opacity. It can improve paper’s whiteness, smoothness, printing adaptability, and increase opacity.
