Properties: high whiteness, strong covering power, make paper stable and white, increase brightness and no transparent, and also increase adsorption ability to ink and color, low abrasion to reduce the bottom abrasion to equipment of paper making and printing. In addition, talc density is lower than TiO2, as filler, talc is more suitable than TiO2, and the price of talc is much lower than TiO2, so talc is much more competitive.
Usage: mainly used as filler in all kinds of paper, it is leading material of high quality paper.
