It is a white pigment with excellent properties. as paper filler used in paper-making industry; it will improve physical and mechanical performance of paper; make paper less transparent and more smooth, and also make paper whiter, more flexible and lustrous, so as to prevent penitration when printing. It is quite even(D50 0.2-0.4) with small particle size, loose particles (bulk density 0.3-0.4) and good hydrophobic dispersion, widely used in paper making and paperboard . It is exported to overseas market and very popular by users.
