Barium sulfate -1AA
Description：
This product adopts German high-end airflow crushing equipment, selected
high content, high specific gravity, high whiteness of natural barite production.
Stable product quality, high whiteness, high purity, the product particle morphology is uniform, narrow particle size distribution, small cut point, low oil
absorption, good mobility, it can avoid the second agglomeration, and the
adaptability is strong. Applied in various high-end coatings with excellent high
temperature resistance and weathering performance, especially in electronic ink
with excellent performance
