Audited Supplier | High purity barium sulfate |
| Chemical formula: BaSO4 |
| Properties: Advanced technology is used to process barium sulfate. The product has high purity and narrow particle size distribution. The unique technology gives the product excellent dispersibility and processing performance, and has better dispersibility with other media systems during application. Affinity, high whiteness, high purity, low iron content (internal control standards are significantly higher than the requirements of the national standard), no mechanical impurities, it is a product with high quality and superior performance among similar domestic products. It can absorb X-rays and gamma rays. It can effectively improve the surface gloss and surface hardness of users' products. |
| Application: paint, ink, coating, plastic, rubber, engineering plastic, friction plate, ceramics, glass, electronics, cosmetics and other fields. |
| Packaging: Plastic woven bags lined with plastic film bags or kraft paper bags, net weight 25kg/bag, and can be packaged according to user requirements. |
