Lithopone is added to plastic resin systems to enhance UV protection of the final plastic products that includes outdoor plastics and automotive plastics. It is used as a white pigment for plastics such as polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate, nylon, and polyoxymethylene (POM). It ensures that UV rays do not penetrate and damage the product and its appearance.
