   2. Description: 

   

  Lithopone  28%-30% is a kind of lithopone whose hiding power is better than that of zinc oxide and worse than that of titanium dioxide.It has good heat-resisitance and is insoluble in water.

   

  White powder, is a mixture of zinc sulfide and barium sulfate. Have high whiteness and good covering power. It is called Inorganic white pigment. Widely used as white pigment of plastics such as polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate, nylon and polyoxymethylene (POM), also for paint and ink . it is use to colourate for rubber products , linoleum, leather, paper, enamel.
