PRODUCT INTRODUCTION
Precipitated Barium Sulfate is a high-purity functional mineral filler produced from high-quality barite ore through grinding, reaction synthesis, filtration, drying and classification. Compared with natural barite powder, it offers better whiteness, lower oil absorption, narrower particle size distribution and more stable chemical properties.
This product is widely used in coatings, paints, powder coatings, marine coatings, plastics, rubber and composite materials. In coating systems, it improves hiding power, surface smoothness, weather resistance and corrosion resistance, and reduces formulation cost. In plastics and rubber, it enhances stiffness, dimensional stability, impact resistance and wear resistance. It is also applied in non-ferrous metal mineral processing as weighting agent and functional additive.
Our precipitated barium sulfate is produced under strict process control. It is available in different grades according to particle size, whiteness, oil absorption, brightness and application requirement. Each batch is inspected for BaSO₄ content, whiteness, oil absorption, particle size, moisture and dispersion performance before shipment.
We provide complete export documents including COA, TDS and SDS for quality traceability and customs compliance. Our technical team can recommend the most suitable grade and dosage according to your material system, production process and destination country regulations.

USAGE NOTES
Dosage Control:
The recommended dosage varies by application, typically from 10% to 40%. Start from lower dosage and adjust according to formulation test and production result.

Dispersion Operation:
Add precipitated barium sulfate gradually into the matrix under stirring, extrusion or grinding. Control dispersion time and shear intensity to avoid particle agglomeration.

Compatibility Check:
Before mass production, test compatibility with resins, polymers, pigments, additives and other fillers. Observe viscosity change, dispersion stability and final product performance.

Process Condition Consideration:
Adjust grade and dosage according to particle size distribution, processing temperature, moisture and final product specification. Fine grades usually require more careful dispersion.

COMMON PROBLEMS IN DOWNSTREAM PRODUCTION
Whiteness Not Meeting Requirement
High iron content, improper ore selection or contamination during handling may reduce whiteness.
Solution: Select high whiteness grade, verify purity and avoid contamination in production.
High Oil Absorption and Viscosity Increase
Fine particle size, high surface area or excessive addition increases coating viscosity.
Solution: Reduce dosage, select coarser grade and optimize dispersant system.
Poor Dispersion and Agglomeration
Insufficient surface treatment, low shear force or unsuitable particle size causes agglomerates.
Solution: Use modified grade, increase dispersion time and optimize processing condition.
Reduced Mechanical Strength in Plastics
Poor interface adhesion, excessive dosage or unsuitable particle size reduces composite strength.
Solution: Reduce dosage, use surface-treated grade and improve interface compatibility.
Low Corrosion Resistance in Marine Coating
Unsuitable grade, poor dispersion or wrong formulation reduces anti-corrosion performance.
Solution: Select marine coating grade, improve dispersion and optimize formulation system.
Low Separation Efficiency in Mineral Processing
Wrong particle size, insufficient weighting effect or unstable pulp density reduces efficiency.
Solution: Select mineral processing grade, adjust dosage and stabilize process parameters.
Customs Detention Due to Mismatched Documents
Incorrect HS code or SDS information triggers inspection and detention at destination ports.
Solution: Confirm destination country regulations before order. Standard export data: HS Code 3824.9999, non-hazardous. We supply consistent full-set SDS / COA documents.
Batch Performance Variation
Changes in raw material, particle size or whiteness cause inconsistent results.
Solution: Standardize production process, inspect whiteness and particle size per batch, and stabilize incoming raw material.
