Product introductionlithopone is a white powder pigment. also known as zinc barium white. It's a mixture of zinc sulfide and barium sulfate. Relative density 4.136-4.39. Insoluble in water, hydrogen sulfide gas is easily decomposed in acid. It doesn't react with hydrogen sulfide and base. It has good heat resistance and improves weather resistance, algae resistance, cost reduction, and whiteness with excellent shielding power. It is easy to oxidize in air and agglomerate in damp. The more zinc sulfide contained, the stronger the hiding power and the higher the quality.Precipitation resulting from the reaction of zinc sulfate with a solution of barium sulfide.  After filtration, drying, and crushing, it is calcined to red heat and dumped into the water to get cold.

 

Application:Widely used as polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate, nylon and polyformaldehyde and other plastics and coatings, paint, ink, plastic, rubber products, lacquer cloth, leather, paper, enamel, etc.
