SG-3000 is a high-purity precipitated barium sulfate manufactured by Yunfu Hongzhi New Materials Co., Ltd. using an exclusive sulfuric acid process with stringent parameter control and multi-stage classification filtration to ensure uniform crystallite size distribution. It is engineered for demanding B2B applications requiring exceptional optical performance, chemical inertness, and processing reliability. Key attributes include ≥99.0 wt% BaSO₄ purity, ultra-high whiteness (L-value ≥99.0), low oil absorption (10 g/100g), neutral-to-alkaline pH (9.0), and minimal moisture content (≤0.3%). This product serves as a premium functional filler and opacifier in industrial coatings, light-diffusing plastics, polyester films, and other advanced material systems where consistent dispersion, UV stability, and surface quality are critical.
1. Ultra-high purity (≥99.0 wt% BaSO₄) ensures minimal interference in sensitive formulations and superior color consistency.
2. Excellent dispersibility and low surface energy enable stable suspension in water- and solvent-based systems without agglomeration.
3. Optimized median particle size (D50 = 3.0 µm) delivers balanced matte finish and efficient visible-light scattering in coatings and films.
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 with resin or solvent using high-shear mixing before incorporation into final formulation. Use appropriate PPE (dust mask, gloves, safety goggles) when handling powdered form to minimize inhalation or skin contact.; Storage condition: bag; Shelf life: bag; Pack size: bag
