NTR-601 is marketed as a high-grade rutile titanium dioxide pigment for plastic applications where both optical cleanliness and processing behavior must meet a higher bar. The product page emphasizes outstanding dispersibility and processing flowability, a blue undertone, strong heat resistance, and good melt flowability. For polymer processors, this combination aims to reduce common problems such as visible specks, shade variation across production runs, and yellowing after high-temperature processing. A blue undertone is also frequently chosen in plastics to counteract slight yellow casts that can appear after repeated heat histories.
The application list includes PE (polyethylene), PVC plastics, PP, ABS, engineering plastics, pipes, and masterbatch, and it is positioned for high-grade plastic specialized products. In masterbatch manufacturing, the pigment needs to disperse rapidly and uniformly at high loading so that downstream converters can dose concentrate reliably and still achieve uniform opacity. In pipes and profiles, heat resistance helps maintain whiteness through long extrusion runs and thick sections. In ABS and engineering plastics, where processing temperatures are often higher, good dispersion and thermal stability help keep the final part looking bright and consistent.
Technical properties are unusually detailed: TiO2 content is 97.0% and rutile content is 98.0%. Dry powder whiteness (CIE L*) is 98.5 and tint reducing power is 1950, supporting strong optical contribution. Oil absorption is 15 g/100 g, which helps preserve melt flow and reduces viscosity build compared with higher-oil-absorption grades. Volatiles at 290°C are listed as ≤ 0.3%, and processing indicators include MFR 28 g/10 min and FPV 0.04 bar/g. It also notes environmental compliance regarding heavy metals and PBBs. Overall, NTR-601 is a premium solution for masterbatch and high-temperature polymer applications.
A: NTR-601 features outstanding heat resistance and low volatiles (≤0.3% at 290°C), ensuring stability and preventing yellowing during high-temperature processing.
A: The blue undertone helps neutralize the natural yellow cast that often occurs in polymers after multiple heat cycles, resulting in a cleaner, brighter white appearance.
A: Yes, it is specifically designed for high-grade masterbatches, offering rapid and uniform dispersibility even at high pigment loadings.
A: Low oil absorption ensures better melt flowability and prevents excessive viscosity buildup, which is critical for maintaining efficient extrusion and injection molding processes.
A: Yes, it contains extremely low levels of heavy metals (Pb, As, Hg, Cr6+ ≤ 10ppm) and is free from PBBs, making it suitable for compliant plastic applications.
