F-100 Modified Ultrafine Precipitated Barium Sulfate is a high-performance functional filler developed by Yunfu Hongzhi New Materials Co., Ltd. using an exclusive sulfuric acid process with stringent parameter control and multi-stage classification filtration. Its nanoscale particle size (D50 = 0.1 µm), narrow distribution, and organic surface modification deliver exceptional dispersion, compatibility, and optical clarity in polymer systems. Widely adopted in engineering plastics, color masterbatches, and transparent masterbatches, it enhances gloss, color vibrancy, mechanical strength, corrosion resistance, and cost-efficiency without compromising transparency. The product is free from sulfides, odors, black specks, and volatile impurities—ensuring high batch-to-batch consistency and processing safety for B2B compounders and masterbatch producers across automotive, packaging, electronics, and construction materials industries.
1. Ultrafine D50 of 0.1 µm ensures superior light transmission and transparency in clear polymers.
2. ≥97.0 wt% BaSO4 purity and ≥98.0% whiteness guarantee high refractive index and brightness.
3. Low oil absorption (16 g/100g) improves melt flow and reduces viscosity during compounding.
4. Neutral pH (8.5) and ≤0.3% moisture ensure thermal stability and prevent degradation in extrusion.
Store in a cool, dry, well-ventilated area away from direct sunlight and moisture. Shelf life is 24 months when sealed and stored under recommended conditions. Transport as non-hazardous general cargo; avoid exposure to rain or high humidity during transit. For optimal dispersion, pre-dry if ambient humidity exceeds 60% RH; use high-shear mixing or twin-screw compounding. Wear appropriate PPE (dust mask, gloves, safety goggles) when handling to minimize inhalation or skin contact with fine powder.; Storage condition: 25 kg multi-layer PE-lined paper bag; Shelf life: 25 kg multi-layer PE-lined paper bag; Pack size: 25 kg multi-layer PE-lined paper bag
