Titanium Dioxide R5566 is a high-performance rutile-type TiO₂ pigment specifically engineered for plastic masterbatch manufacturing. Produced via the chloride process, it features an ultra-fine particle size distribution and advanced inorganic/organic surface treatment that ensures exceptional dispersibility within polyolefin, PVC, ABS, and engineering plastic carrier systems.
With a TiO₂ content exceeding 93%, R5566 delivers outstanding whiteness (L* ≥ 98), high hiding power (scattering coefficient ≥ 1700 m²/kg), and excellent UV durability — making it the preferred choice for manufacturers who demand consistent, batch-stable masterbatch quality at industrial scale.
🏆 R5566 is trusted by masterbatch producers across 30+ countries for its unmatched consistency, easy processing, and long-term color stability in demanding plastic applications.

The global plastic masterbatch market is projected to surpass USD 18 billion by 2030, with white masterbatch — heavily dependent on high-quality rutile TiO₂ — accounting for the largest segment. Here's what's shaping the industry:
The rise of e-commerce, flexible food packaging, and sustainable consumer goods packaging is driving unprecedented demand for high-opacity white masterbatches. R5566-grade TiO₂ enables thinner film gauges while maintaining full opacity, reducing material costs by up to 15%.
China, India, Southeast Asia, and South Korea collectively represent over 55% of global masterbatch production capacity. Regional manufacturers increasingly prefer chloride-process rutile TiO₂ like R5566 for its superior performance in high-speed extrusion environments and stringent food-contact compliance requirements.
Brand owners and regulators are pushing for recyclable and mono-material packaging. R5566's compatibility with recycled polyolefin streams and its ability to maintain whiteness after reprocessing cycles makes it a future-proof choice for circular economy-aligned production lines.
Modern masterbatch compounding lines operate at screw speeds exceeding 600 RPM. R5566's optimized organic surface treatment ensures thermal stability up to 280°C and prevents yellowing or plate-out during intensive twin-screw extrusion, meeting the demands of next-generation compounding equipment.
Beyond standard white masterbatch, R5566 is increasingly specified in UV-stabilized agricultural films, infrared-reflective roofing membranes, and anti-counterfeiting masterbatches — sectors where TiO₂ functionality extends well beyond simple whitening.
Post-pandemic supply chain disruptions have accelerated the shift toward regionalized TiO₂ sourcing. Asia Pacific Chemicals' 2,000-ton warehousing infrastructure and multi-manufacturer supply network directly address this need, offering masterbatch producers reliable just-in-time delivery.
Titanium Dioxide R5566 is not a one-size-fits-all pigment — its engineered surface chemistry unlocks specific performance advantages across diverse plastic processing sectors.
R5566 achieves outstanding opacity at loading levels as low as 40–50% in LDPE/LLDPE carrier systems. Its narrow particle size distribution prevents filter screen clogging in high-throughput blown film lines, while low oil absorption ensures excellent melt flow index retention — critical for thin-gauge packaging film production.
In engineering plastic systems processed above 240°C, R5566's inorganic coating provides a thermal shield that prevents TiO₂-catalyzed photo-oxidation. The result is excellent long-term color stability in automotive interior parts, electrical housings, and consumer appliance components that require consistent white appearance over product lifetimes exceeding 10 years.
Agricultural film manufacturers specify R5566 for its dual functionality: high light reflectance to manage soil temperature and UV-scattering capability that extends film service life in outdoor environments. Combined with HALS stabilizers, R5566-based masterbatches deliver greenhouse films with 3–5 year outdoor durability ratings.
In rigid PVC window profiles and pipes, R5566 provides the whiteness and UV protection essential for 25+ year outdoor performance warranties. Its compatibility with calcium-zinc and lead-free stabilizer systems makes it the preferred TiO₂ grade for modern, RoHS-compliant PVC formulations used in sustainable construction applications.
Textile-grade masterbatch producers value R5566 for its consistent particle size that controls fiber delustering uniformity. In polyester staple fiber and filament production, precise TiO₂ loading creates the desired semi-dull or full-dull appearance without compromising fiber tensile strength or spinnability at high draw ratios.
For household goods, cosmetic packaging, and food-contact containers, R5566 meets FDA 21 CFR and EU 10/2011 food contact regulations. Its excellent dispersibility in PP and HDPE carrier systems enables masterbatch producers to achieve uniform color development without agglomeration streaks, even at high pigment concentrations of 60–70% TiO₂.
