We use sulfuric acid and barium carbonate as raw materials to produce precipitated barium sulfate by sulfuric acid process. The product has the characteristics of controllable particle size, controllable shape, high whiteness, no sulfide, no black spot impurities, good dispersion and good thixotropy. The average particle size is 30 nm to 10 μm. A variety of surface-treated precipitated barium sulfate can be customized according to customers' requirements.

The functional masterbatch is made of nano inorganic functional materials and plastic carriers by adopting the independently developed new process and new nano technology. The product has high transparency, enhanced mechanics, good dispersibility, non-toxic and harmless, corrosion resistance and other properties. Functional masterbatch is widely used in the fields of continuous roll bags, protective films...
