Features:
Using advanced domestic synthesis technology, the internal quality control standards are significantly higher than national standards, with high main content, narrow particle size distribution, ultra-fine particles, high whiteness, low iron content, and ultra-fine processing of barium sulfate. The production process is advanced, and the excellent dispersibility provides users with particularly superior processing performance. It exhibits good dispersibility and affinity with other media systems during application, with no mechanical impurities. It is currently a product with superior quality and performance among similar domestic products, capable of absorbing X-rays and gamma rays, effectively enhancing the surface gloss and hardness of user products. Applications:
Widely used in fields such as paint, ink, coatings, plastics, rubber, chips, 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.
