Huachuang Barium Sulfate Precipitated for Powder Coating 1250 Mesh
Product Overview
Nanfeng Barium Sulfate Precipitated (Model F-268-1250) is a high-performance, ultra-fine synthetic barium sulfate powder engineered for precision applications across coatings, plastics, rubber, and specialty industries. With a controlled particle size of 1250 mesh (D50: 10–15 µm) and a purity level exceeding 98%, this chemically inert filler delivers unmatched opacity, thermal stability, and environmental resistance. Packaged in 25 kg/bag with dual-layer PE-lined woven polypropylene bags, it ensures moisture-proof integrity and ease of handling for global industrial supply chains.
Certified under ISO 9001 and ISO 14001 standards, F-268-1250 is the ideal choice for formulators seeking to enhance product durability, reduce costs, and comply with stringent regulatory frameworks such as REACH, RoHS, and FDA 21 CFR.
Key Product Features
1. Superior Physicochemical Properties

- Density & Thermal Resilience:
- Relative density: 4.50 g/cm³ at 15°C (ISO 1183-1:2019).
- Melting point: 1,580°C, suitable for high-temperature processes (e.g., powder coatings, ceramic sintering).
- Chemical Inertness:
- Insoluble in water, ethanol, and most acids (solubility <0.0025 g/100mL at 20°C).
- Soluble in hot concentrated sulfuric acid for specialized synthesis.
- Anti-Caking Performance: Advanced surface modification minimizes agglomeration during storage (Hausner ratio ≤1.25, ISO 3953).
2. Functional Advantages
- Optical Enhancement:
- Reflectivity ≥92% (ASTM E1347) for brightening coatings and plastics.
