Product Information
R-213 is positioned as a premium rutile titanium dioxide pigment for high-quality masterbatch and color sheet applications, with attention to both processing cleanliness and regulatory suitability. The product conforms to FDA regulations for materials in contact with food, which is relevant for certain packaging and consumer goods uses. It is described as hydrophobic with low involatile content to enhance lacing resistance in plastic processing.
Optically, R-213 emphasizes excellent whiteness with a blue undertone, high dispersibility, and good melt flow. For masterbatch producers, these traits support higher pigment loading while keeping compounding stable, helping downstream converters achieve target opacity at lower let-down rates. A blue undertone helps finished polymer parts appear brighter, especially in resins that tend to pick up slight yellowing after heat history.
The technical profile supports "premium plastic" positioning with 97% TiO2 content and Al2O3 inorganic surface treatment. With an ISO classification of R1 and a color difference control of Delta E ≤ 0.5, it ensures uniform appearance and shade control critical for packaging sheets, thin films, and visible consumer components.
