GBASEA High Gloss Barium Sulfate 5HB for Coatings and Rubber Industries
Product Overview
GBASEA High Gloss Barium Sulfate 5HB is a premium-grade, surface-treated inorganic filler engineered to deliver exceptional gloss, mechanical strength, and chemical resistance in coatings, rubber, and composite applications. With a controlled particle size distribution (D97 ≤2 µm) and a purity level exceeding 99.3%, this advanced barium sulfate grade enhances surface smoothness, light reflectivity, and abrasion resistance while maintaining excellent dispersion stability in polar and non-polar matrices. Ideal for high-gloss automotive coatings, premium rubber goods, and industrial composites, GBASEA 5HB combines the benefits of ultra-fine micronization with proprietary surface modification to address critical challenges in formulation efficiency, sustainability, and end-product performance.
Processed via a multi-stage refining and silane treatment process, GBASEA 5HB minimizes resin demand, reduces VOC emissions, and improves processing flow in solvent-based, waterborne, and solvent-free systems. Its low oil absorption (≤14 g/100g) and high refractive index (1.64) make it indispensable for replacing TiO₂ in cost-sensitive formulations, while its halogen-free, REACH-compliant profile ensures compliance with global environmental standards. Trusted by leading manufacturers in automotive, construction, and rubber industries, GBASEA 5HB empowers engineers to achieve mirror-like finishes, extended product lifespans, and reduced carbon footprints.
