Product Description
Precipitated Barium Sulfate 98% - High Whiteness Filler
Precipitated barium sulfate is a high-purity barium sulfate (BaSO₄) produced through chemical synthesis. This white ultra-fine powder features narrow particle size distribution, high whiteness (≥98%), exceptional chemical inertness, high density (4.5 g/cm³), and high refractive index (1.64). Compared to natural barite powder, it offers superior purity, particle size control, and performance consistency, making it an essential functional inorganic material for high-end manufacturing applications.
Core Applications
Optical Performance in High-End Coatings and Inks
- Opacity and Gloss Enhancement: Maximizes light scattering for superior hiding power and mirror-like effects
- Durability Improvement: Enhances abrasion resistance, weatherability, and chemical resistance
- Functional Applications: Used in antimicrobial, conductive, and radiation shielding coatings
Reinforcement in Engineering Plastics and Rubber
- Dimensional Stability: Improves rigidity, heat resistance, and reduces warpage
- Optical Performance: Ideal for high-transparency, high-gloss plastic products
- Functional Modification: Enables anti-static, thermally conductive, and sound insulation materials
Medical and Protection Applications
