Barium sulfate( friction disk) :produced by advanced physical process, after the special modification, the performance is more superior, high whiteness, narrow and uniform particle distribution ,good dispersion , super fine, super clean and so on.
Application: Can absorb the X-ray, γ-rays, and give high density and surface finish degree, widely used in paint, ink, coating, plastic, rubber, jetton, friction plates, ceramics, glass, electronics, cosmetics, pharmaceuticals, food and ect.
