Application:
1. It can be used as the filler of paints and coatings to replace the expensive raw materials such as precipitated barium sulfate, lithopone, titanium dioxide and active silica. It is suitable for controlling the viscosity of paints and making the products bright and stable.
2. Used in plastic industry - it can be used as the filler of ABS raw material to make the product lustrous and bright, and improve the strength, rigidity and wear resistance of the product.
3. It is used in rubber industry. Products under 500 mesh can be widely used in rubber products as fillers to reduce cost, improve hardness, acid and alkali resistance and water resistance of products, and has good reinforcing effect on natural rubber and synthetic rubber.
4. Used in paper industry - high fineness barite powder can be used as filler and coating filler for white board paper and copper board paper to improve whiteness and surface coverage. Product index:
Chemical substance: Precipitated barium sulfate (BaSO4) / precipitated product status: white powder
