Detailed Information
R-5568 is positioned as a rutile titanium dioxide pigment for plastics and masterbatch production, where processing rheology and dispersion efficiency are critical. The product page states that it is stabilized with zinc salt and then finished with inorganic coating and organic surface treatment. It is described as having easy dispersion, high hiding power, low oil absorption, good weather resistance, good system compatibility, and excellent processing rheological properties. For polymer compounders, low oil absorption is often linked to lower viscosity contribution, which helps maintain melt flow and throughput at a given pigment loading.
The applications listed are plastics and masterbatches, which covers a wide set of conversion processes such as injection molding, extrusion, blow molding, and film production. In masterbatch manufacturing, dispersion quality determines how reliably the concentrate can be used by converters: better dispersion reduces specks and streaks, improves opacity at lower let-down, and helps keep shade stable over time. In molded and extruded products, high hiding power can reduce the amount of pigment required to achieve full coverage, supporting cost efficiency and helping retain mechanical properties. From a processing standpoint, stable feeding, adequate shear in the compounding step, and control of moisture are all practical steps to realize the pigment’s stated dispersion and rheology benefits.
The technical properties on the page align with the processing-focused description. TiO2 content is ≥ 94.0% and rutile content is ≥ 98.0%. Lightness is ≥ 94.30, and hiding power (Reynolds number) is ≥ 1860. The oil absorption value is listed as ≤ 18 g/100 g, which supports the goal of preserving melt flow. Cleanliness and stability indicators include residue on a 25 um sieve ≤ 0.02% and volatiles at 105°C ≤ 0.6%. The aqueous suspension pH range is 6.0–9.0, and electrical resistance of aqueous extract is ≥ 60 ohm·m. Taken together, these specifications and the zinc-salt stabilization claim position R-5568 as a plastics-oriented rutile TiO2 for customers who prioritize opacity, easy dispersion, and stable processing behavior in masterbatch and polymer conversion.
