Special-use barium sulfate (special for friction plate) is produced in advanced production techniques,
specially modified, excellent performance, high whiteness and even and narrow distribution of particle
size, good dispersibility, super-fine; can absorb X-ray, and endow the materials with high density and surface finish, therefore widely used in paints,
printing ink, coating, plastics, rubber, chips, friction plate, ceramics, glass, electronics, cosmetics,
pharmacy and food etc.
