Product Description:
Modified barium sulphate undergoes a meticulous chemical treatment that enhances its surface properties.
The surface whiteness of the barium sulphate powder is increased, while the purity is unchanged and the particle size is more uniform. Modified barium sulphate powder can achieve excellent effects in various application fields.
Modified Precipitated Barium Sulphate is a surface-treated, high-purity BaSO₄ material engineered to improve dispersion performance and resin compatibility in demanding industrial applications. Through controlled chemical modification, the surface properties of precipitated barium sulphate are optimized while maintaining high purity and uniform particle size distribution.
Compared with ordinary precipitated grades, Modified Precipitated Barium Sulphate offers higher surface whiteness, improved interfacial affinity with polymers, and lower oil absorption. It is widely used in high-end coatings, automotive paint systems, engineering plastics, and functional masterbatch formulations where gloss, mechanical strength, and dimensional stability are critical.
Key Features of Modified Precipitated Barium Sulphate
Superior Dispersibility
The surface-treated structure ensures smooth dispersion in resin systems, reducing agglomeration and preventing pockmarks. It supports high-gloss coatings and uniform film formation.
Odourless and Sulfide-Free
Unlike conventional processes, our Modified Precipitated Barium Sulphate contains no unpleasant odor or sulfide residues, ensuring cleaner processing in enclosed manufacturing environments.
Enhanced Resin Affinity
Surface modification improves compatibility with PP, PE, ABS, PVC, and other thermoplastics. This results in better mechanical strength, improved interfacial bonding, and stable long-term performance.
Low Oil Absorption
Reduced oil absorption value lowers binder demand in coating and masterbatch systems. This allows higher filling ratios, improved processing efficiency, and optimized formulation cost.
Stable Whiteness
High whiteness retention supports consistent color masterbatch performance and prevents shade fluctuation in plastic and coating applications.
Applications of Modified Precipitated Barium Sulphate
High-End Coatings
Widely used as a functional filler for high gloss industrial coatings, powder coatings, solvent-based topcoats, and UV-curable systems.
In automotive topcoat formulations and marine anti-corrosion coatings, Modified Precipitated Barium Sulphate improves gloss level, scratch resistance, and film density.
Automotive and Marine Coatings
Enhances brightness and leveling in automotive refinish paint, OEM automotive coatings, and marine protective coatings exposed to harsh environments.
Plastics and Engineering Plastics
Used as a high density functional filler in PP injection molding, PE blown film, ABS housings, and PVC extrusion profiles.
In engineering plastics, Modified Precipitated Barium Sulphate improves rigidity, dimensional stability, and surface smoothness without compromising processability.
Color and Functional Masterbatch
Acts as a dispersion-enhancing carrier in color masterbatch production.
Supports high gloss PP masterbatch, PE film masterbatch, and filler masterbatch systems requiring stable whiteness and controlled particle size distribution.
Printing Inks and Industrial Inks
Provides improved rheology control and brightness in offset printing inks, gravure inks, and screen printing formulations.
Rubber Products
Applied in abrasion-resistant rubber compounds, industrial rubber sheets, and sealing materials to increase density and mechanical reinforcement.
