Blanc finetm bsp is a chemically synthesized barium sulfate product (blanc fixe) refined through special manufacturing processes with highly pure barium salt and sodium sulfate as its raw materials. Its grain sizes are under strict control in the course of reactions and synthesis and content of impurities is minimized. It features low specific weight, gentle and stable nature, narrow distribution of grain sizes, extremely good light fastness, weathering resistance and other outstanding chemical properties. Blanc finetm bsp may be used for thermoplastics to improve the rigidity, hardness and abrasion resistance of plastic products. Blanc finetm bsp is approved for the product subject to contacting food due to its nontoxic property. The brightness over 94 and near spherical crystal shape of blanc finetm bsp make it easier to well distribute in each corner in formula, thereby achieving a dense, exquisite, tough and smooth product appearance of uniform color Blanc finetm bsp is free from impurities hazardous to elastomer. Hence blanc finetm bsp is particularly suitable to the filler for elastomer. Its other advantages include outstanding rheological property, low abrasiveness and high chemical purity.
