Lithopone, a blend of zinc sulfide and barium sulfate, is renowned for its exceptional properties. It boasts high refractive index, superior lightfastness, and excellent heat resistance—qualities that make it particularly suitable for rubber compounding. When integrated into rubber formulations, lithopone imparts a pristine white color, which not only improves the aesthetic appeal of the final products but also serves functional purposes.
