High Whiteness Nantai Titanium Dioxide NR-9501 for Plastic, Ink, Coating - Superior Brightness and Coverage

Nantai Titanium Dioxide NR-9501 stands as a benchmark in pigment technology, engineered to deliver unmatched brightness, opacity, and durability across industrial applications. This high-purity rutile titanium dioxide (TiO₂) combines advanced surface treatment and particle size optimization to meet the stringent demands of plastics, inks, and coatings. With a whiteness index exceeding 98% (ISO 2470) and superior light-scattering efficiency, NR-9501 enables manufacturers to achieve premium aesthetics while optimizing production costs.

‌Technical Excellence‌

Nantai NR-9501 is produced through chloride process refinement, ensuring chemical purity (>92% TiO₂ content) and controlled particle morphology (median size 0.2–0.3 µm). Proprietary alumina-silica surface modification enhances dispersion stability and interfacial compatibility with organic matrices. Key specifications include:

• ‌*Brightness (L value)**‌: ≥98.5 (CIE-Lab system)
• ‌Oil Absorption‌: 18–22 g/100g (ASTM D281)
• ‌pH Stability‌: 6.5–7.5 (10% aqueous suspension)
• ‌Weather Resistance‌: 1,500+ hours QUV-B exposure without chalking (ASTM G154)
• ‌Relative Scattering Power (RSP)‌: 105–110% vs. standard rutile grades

‌Performance Advantages‌

‌1. Unrivaled Optical Properties‌

• ‌Whiteness Optimization‌: Achieves ΔE <0.5 in color-critical applications, ideal for white masterbatches and premium packaging

• ‌Circular Economy‌: Compatible with PCR plastics up to 50% recycled content
• ‌Food Safety‌: NSF/ANSI 51-certified for food-contact polymers

‌Formulation Guidelines‌

• ‌Plastics Compounding‌: Pre-dry at 110°C for 2 hours; optimize screw RPM to avoid shear-induced discoloration
• ‌Coating Dispersions‌: Use polyacrylate dispersants at 0.3–0.5% active content; target Hegman fineness ≥6.5
• ‌Ink Systems‌: Combine with 5–8% hyperdispersants for submicron particle distribution

‌Packaging & Logistics‌

• ‌Moisture-Proof Bags‌: 25 kg multi-layer kraft paper with PE inner lining
• ‌Bulk Options‌: 1-ton super sacks with RFID tracking and UV protection
• ‌Storage‌: 24-month stability in <30% RH environments at 10–35°C
• ‌Global Compliance‌: Meets IMDG/IMO transport regulations for hazardous materials exemption

‌Strategic Value Proposition‌
