Application characteristics: Precipitated barium sulfate is an amorphous white powder produced by chemical precipitation method. Its physical properties, purity and whiteness are better than those of superfine natural barium sulfate. It has good light resistance, weather resistance, acid resistance, flame retardant and electrical insulation. Because of its excellent chemical inertia and moderate surface energy, it has good dispersion and stability as a functional filler and physical pigment. At the same time, it has better storage stability and covering power than superfine barium sulfate. It can partly replace titanium dioxide in plastics, reduce the amount of pigment added and reduce the product cost. NB series nano composite barium adopts high-tech nano manufacturing technology. The particles are coated with inorganic modified additives. It has the characteristics of high whiteness, small particle size, narrow distribution range, high activation, good dispersion and high gloss. It is widely used in various inks, plastics and high-end coating materials. It can make the products maintain excellent transparency, brightness, good dispersion, low oil absorption value, and improve the product quality It can improve the surface gloss, color rendering, adhesion and weather resistance of the products, and reduce the cost of the products.
