Pangang R-248 General-purpose Rutile Grade TiO₂

Pangang R-248 is a general-purpose rutile grade titanium dioxide featuring high whiteness, strong hiding power, and excellent durability. Its optimized particle size distribution, advanced surface treatment system, and stable crystalline structure provide consistent performance across polymer applications, solvent-based and water-based coating systems, and high-concentration masterbatches. R-248 titanium dioxide is widely used in industries requiring high opacity, stable processing performance, and long-term color retention, such as in plastics, coatings, inks, and masterbatch applications.

R-248+ is a refined version of R-248, featuring improved purity, lower volatiles, and better dispersion in demanding processing environments.

Features & Advantages of Pangang R-248

High Whiteness & Blue Undertone. The optimized particle size distribution and rutile crystal structure provide high brightness, strong light scattering, and a clean blue-toned white appearance.
Strong Hiding Power & High Tinting Strength. Its high opacity ensures efficient coverage and reduces pigment consumption in formulations, making it ideal for plastics and coatings that require high chromatic purity.
Superior Dispersibility & Wetting Properties. The surface treatment allows easy dispersion in polymer systems, coatings, and inks. It resists agglomeration and offers stable performance during processing and long-term storage.
Good Processability & Rheology. Low oil absorption ensures favorable flow properties in plastic extrusion, injection molding, masterbatch production, and other high-shear processes. It does not significantly affect melt viscosity.
High Durability, Weatherability & UV Resistance. The Zr–Al coating system provides excellent resistance to UV radiation, chalking, yellowing, and chemical attack. Suitable for outdoor applications and long-service-life plastic products.
Broad Compatibility. R-248 shows excellent compatibility with polyolefins (PE, PP), PVC, ABS, PS, EVA, PET, PC,water-based and solvent-based coatings,printing inks,paper, leather finishes, and other industrial formulations.
