H-700 is a high-purity precipitated barium sulfate engineered for demanding B2B applications in advanced materials manufacturing. Produced via a proprietary sulfuric acid process with strict parameter control and multi-stage分级 filtration, it delivers exceptional crystallinity uniformity and narrow particle size distribution. Its ultra-high purity (≥99.0% BaSO₄), near-neutral pH (8.0), low moisture content (≤0.3%), and outstanding whiteness (≥98.0%) make it ideal for performance-critical formulations. Key industrial uses include polyester fiber production, electronic conductive inks, engineering-grade modified plastics, and high-gloss industrial coatings—where consistent dispersion, chemical inertness, and optical clarity are essential. The product enhances dimensional stability, surface smoothness, and pigment efficiency without compromising rheology or long-term durability.
1. Ultra-narrow particle distribution: D50 = 0.7 µm ensures uniform dispersion and eliminates agglomeration in polymer matrices.
2. Exceptional purity ≥99.0% BaSO₄ with zero detectable sulfides, odor, or impurities—critical for electronics and food-contact-adjacent applications.
3. Low oil absorption (12 g/100g) reduces resin demand and improves formulation efficiency in plastics and coatings.
Store in a cool, dry, well-ventilated area away from direct sunlight and moisture. Shelf life is 24 months when sealed and stored under recommended conditions. Transport as non-hazardous general cargo; avoid exposure to rain or condensation during transit. For optimal dispersion, pre-mix using high-shear mixing or ultrasonication before incorporation into final formulations. Use appropriate PPE (dust mask, gloves, safety goggles) when handling to minimize inhalation of fine particles; not classified as hazardous per GHS but avoid prolonged airborne exposure.; Storage condition: 25 kg bag; Shelf life: 25 kg bag; Pack size: 25 kg bag
