Detailed 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 page states that it conforms to FDA regulations for materials in contact with food, which is relevant for certain packaging and consumer goods uses. It is also described as hydrophobic with low involatile content to enhance lacing resistance in plastic processing. In practice, this type of positioning targets compounders who want a white pigment that disperses well and keeps the melt stable, while also minimizing surface defects that can appear as streaks or “lace” patterns in films and sheets.
Optically, the page 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, and they help downstream converters achieve target opacity at lower let-down rates. A blue undertone can help finished polymer parts appear brighter, especially in resins that tend to pick up slight yellowing after heat history. Because the product is aimed at high-quality masterbatches, it is well suited to applications where uniform appearance and shade control are critical, such as packaging sheets, thin films, and visible consumer components.
The technical table on the product page supports the “premium plastic” positioning. TiO2 (ISO 591-1) is listed as 97% with alumina (Al2O3) inorganic surface treatment and organic surface treatment. ISO classification is R1 and the stated color difference control is Delta E ≤ 0.5. Density is 4.2 g/cm3 and dry powder whiteness (CIE L*) is 98.0. Relative scattering power is reported as 95–105%, and oil absorption is 15 g/100 g, which supports strong opacity with a relatively low rheology penalty in polymer systems. Volatiles at 105°C at packaging are listed as 0.2%. Overall, R-213 is positioned as a bright, well-dispersing rutile TiO2 for masterbatch users who want strong whiteness, stable processing, and suitability for food-contact related applications where required.
