2015/03/01  bmschem

    Barium sulfate dedicated to glass clarifys glass products in glassmaking industry. Ultrafine barium sulfate is made of high grade barium sulfate ore and produced by international leading technology. This product is dense particles with narrow particle size distribution, high chemical stability, more than 98% barium sulfate, high brightness, no spots, no impurities, good dispersity, good wettability, excellent acid resistance, heat resistance and corrosion resistance. It can significantly improve product hardness and wear resistance.

     Product features:

1   Narrow particle size distribution, smaller specific area and dosage of basic material, obtaining high gloss and liquidity;

2   Inert chemicals, high acid and alkali resistance, good sunscreen and weatherability;

3   High purity, less impurity, no trace minerals and salt impurities (no corrosion or sulfide composition);

4   Improving product strength, wear resistance and geometric stability;

5   Good compatibility with matrix, tight coupling;

6   Stable pigments;

7   Easy dispersibility;
