1250 메쉬 수정된 초미세 침전 황산바륨 - 코팅용 초미세 분말
Product Overview
Modified Ultrafine Precipitated Barium Sulfate represents a next-generation functional filler engineered through advanced crystallization and surface modification technologies. Unlike conventional barium sulfate, this ultrafine variant combines nano-scale particle control (D50: 0.2–0.5 μm) with organosilane coupling agents to deliver unparalleled dispersion stability, interfacial adhesion, and process adaptability across coatings, polymers, and specialty chemical formulations. Certified to ISO 3262-7 standards, it achieves 98% purity with <50 ppm heavy metal content, making it ideal for applications demanding both performance excellence and regulatory compliance (REACH/ROHS/GB9685).
