Features:Using advanced organic modification technology, the product undergoes ultra-fine processing of barium sulfate, resulting in high purity and a narrow particle size distribution. The unique organic modification technology endows the product with excellent dispersibility and processing performance, offering good dispersion and affinity with other media systems during application. With high whiteness, high purity, low iron content (internal control standards significantly exceed national standards), and no mechanical impurities, it is currently a product of superior quality and performance among similar domestic products. It can absorb X-rays and gamma rays, effectively enhancing the surface gloss and surface hardness of user products.
Usage:In fields such as paint, ink, coatings, plastics, rubber, engineering plastics, friction materials, ceramics, glass, electronics, and cosmetics.
Packaging:Packaged in plastic woven bags lined with plastic film bags or kraft paper bags, with a net weight of 25kg per bag. Packaging can also be customized according to user requirements.
