High Hiding Power Nantai Rutile Titanium Dioxide NR-930 for Plastic & Papermaking
Product Overview
Nantai NR-930 Rutile Titanium Dioxide redefines industrial pigment performance through precision-engineered inorganic-organic hybrid surface engineering. Combining SiO₂-Al₂O₃ dense inorganic coating with customizable organic treatments, this pigment achieves TiO₂ content ≥94% and rutile crystallinity ≥98%, delivering superior hiding power (Reynolds index ≥2,800) and universal compatibility across solvent/water-based systems. Certified to ISO 9001 and REACH standards, NR-930 enables 15–20% opacity gains versus conventional rutile TiO₂ grades while maintaining oil absorption ≤21 g/100g and Hegman grind ≥5.5, making it the optimal choice for architectural coatings, industrial plastics, powder coatings, and specialty applications.
Produced via wet sand-milling technology with D50 particle size 0.25–0.35 µm, NR-930 ensures narrow size distribution (PSD <1.2) for maximized light scattering. Available in spot purchases or bulk contracts, this pigment supports global supply chains with 99% batch-to-batch consistency and ≤7-day lead times.
