Key Features & Advantages
-
Ultra-High Purity & Consistency
- Purity ≥98.5%: Minimal impurities (Fe, Cl⁻, moisture) ensure optimal compatibility with resins, polymers, and additives, reducing the risk of discoloration or destabilization.
- Uniform Particle Size (D50: 1–3 μm): Tightly controlled particle distribution enhances dispersion in matrices, minimizing agglomeration and improving surface finish.
- Low Oil Absorption (14–18 g/100g): Reduces binder demand in coatings and plastics, lowering formulation costs without compromising performance.
-
Superior Functional Performance
- High Refractive Index (1.64): Delivers excellent opacity and brightness in paints, coatings, and masterbatches, reducing the need for TiO2 or other costly pigments.
- Chemical Inertness: Resistant to acids, alkalis, and solvents, ensuring long-term stability in harsh environments.
- Thermal Stability (>1,600°C): Withstands high-temperature processing in plastics and ceramics without decomposition or yellowing.
-
Enhanced Mechanical Properties
- Improves hardness, abrasion resistance, and dimensional stability in engineering plastics (e.g., PA, PBT, PVC) and rubber products.
- Reinforces composite materials (e.g., fiberglass, adhesives) by increasing tensile strength and impact resistance.
-
Eco-Friendly & Compliant
- Heavy metal-free (meets RoHS, REACH, and FDA standards for indirect food contact applications).
- Low dust generation and VOC-free composition align with sustainable manufacturing practices.
Applications
Zibo Hongfang Precipitated Barium Sulfate is a versatile additive across industries:
1. Coatings & Paints
- Architectural & Industrial Coatings: Enhances opacity, weather resistance, and scratch resistance in water-based and solvent-based systems.
- Automotive Coatings: Improves UV stability and surface smoothness in primers, basecoats, and clearcoats.
- Powder Coatings: Optimizes flow properties and electrostatic spray efficiency.
2. Plastics & Polymers
- Engineering Plastics: Boosts stiffness, heat deflection temperature (HDT), and flame retardancy in automotive components, electronic housings, and consumer goods.
- PVC Products: Acts as a cost-effective filler in pipes, profiles, and cables, improving density and processability.
- Thermoplastics & Elastomers: Enhances mold release, reduces shrinkage, and improves surface gloss in injection-molded parts.
3. Specialty Applications
- Printing Inks: Delivers high gloss and printability in gravure and flexographic inks.
- Rubber Industry: Increases density and abrasion resistance in seals, gaskets, and tires.
- Cosmetics & Pharmaceuticals: Serves as a safe, inert filler in creams, lotions, and tablet coatings (pharmaceutical-grade options available).
