Nantai Universal Rutile Titanium Dioxide NR-960 - High Purity for Plastic and Coating Applications
Nantai Universal Rutile Titanium Dioxide NR-960 sets a new standard in high-performance pigments, engineered to deliver exceptional optical and durability properties across diverse industrial applications. This premium-grade rutile TiO₂ combines advanced inorganic/organic surface treatments with precision particle engineering, making it the go-to choice for plastics, coatings, inks, and specialty material formulations. Processed through cutting-edge wet grinding technology using imported milling systems, NR-960 achieves a narrow, optimized particle size distribution (D50: 0.2–0.3 µm) that maximizes light scattering efficiency while ensuring effortless dispersion.
Technical Superiority
Advanced Surface Architecture
The NR-960 pigment undergoes dual-phase surface modification for unmatched performance:
- Inorganic Coating: A proprietary blend of zirconium oxide (ZrO₂) and aluminum oxide (Al₂O₃) forms a durable protective shell, enhancing weather resistance and chemical stability.
- Organic Treatment: Specialized siloxane coupling agents improve compatibility with polymeric matrices, reducing interfacial tension in hydrophobic systems.
Precision Manufacturing
- Wet Grinding Process: Achieves particle uniformity (Span value <1.2) through German-engineered bead mill technology
- Surface Area Control: 8–12 m²/g BET surface area optimizes packing density
- Crystal Purity: >94% rutile content with controlled anatase phase elimination
Key Performance Advantages
1. Unmatched Optical Properties
- Whiteness Index: ≥98 (ISO 2470) with ΔE <0.3 batch consistency
- Gloss Enhancement: Delivers 85–95 GU at 60° in automotive topcoats (ASTM D523)
- Tinting Strength: 1,800–2,000 RTU (Relative Tinting Units) versus industry standard
2. Enhanced Durability
- Weather Resistance: 2,000+ hours QUV-B exposure without chalking (ASTM G154)
- Thermal Stability: Maintains color integrity at processing temperatures up to 320°C
- Chemical Resistance: Withstands 5% HCl/NaOH solutions for 240h (ISO 2812-1)
3. Formulation Efficiency
- Oil Absorption: 16–18 g/100g (ASTM D281), reducing resin demand by 12–15%
- Dispersibility: Achieves Hegman fineness 7+ within 30min milling (ISO 1524)
- Moisture Resistance: <0.3% water absorption ensures free-flowing powder properties
Multi-Industry Applications
Coatings & Paints
- Architectural Coatings: Enables 85% PVC formulations with 50µm crack bridging capability
- Powder Coatings: Delivers 95% first-pass transfer efficiency in electrostatic spraying
- Marine Systems: Reduces biofilm adhesion by 40% through hydrophobic surface properties
Plastics & Polymers
- Engineering Plastics: Maintains impact strength in PA6/GF composites at 15% loading
- Masterbatches: Achieves <0.5% filter pressure rise in fiber-grade PET processing
- Films & Sheets: Ensures >90% light transmission in 50µm BOPP packaging films
Specialty Applications
- Inks & Toners: Provides 220% ink transfer efficiency in gravure printing
- Rubber Products: Enhures UV resistance in EPDM roofing membranes
- Paper Coating: Achieves 92% ISO brightness with 30% lower calendering pressure
Sustainability & Compliance
- Energy-Efficient Production: 30% lower carbon footprint vs. conventional sulfate-process TiO₂
- Global Certifications: Compliant with REACH, RoHS, and FDA 21 CFR 175.300
- Circular Economy: Compatible with 50% PCR plastic content in injection molding
Formulation Guidelines
- Coating Systems: Use with polyacrylate dispersants (0.2–0.5% active) for optimal stabilization
- Plastic Compounding: Pre-dry at 110°C×2h; maintain screw speed <800 RPM to prevent shear degradation
- Ink Manufacturing: Combine with 5–8% hyperdispersants for submicron particle distribution
Packaging & Logistics
- Moisture-Proof Options: 25kg multi-layer kraft bags with PE liner (0.03g/m²/24h WVTR)
- Bulk Solutions: 1-ton super sacks with RFID tracking and UV-resistant coating
- Global Compliance: Non-hazardous classification per IMDG/IMO regulations
Why NR-960 Stands Out
- Cost-Performance Balance: Reduces TiO₂ usage by 15–20% through enhanced hiding power
- Process Adaptability: Suitable for water-borne, solvent-borne, and 100% solid systems
- Technical Support: Custom surface treatments available for niche applications
- Supply Chain Reliability: Dual-source manufacturing with ISO 9001-certified quality control
From high-gloss automotive finishes requiring flawless aesthetics to heavy-duty industrial coatings demanding decade-long durability, Nantai NR-960 delivers uncompromising performance. Its unique combination of inorganic durability and organic compatibility makes it the smart choice for formulators seeking to push material boundaries while maintaining production efficiency.
