Information
NR-930 is presented as a rutile titanium dioxide pigment oriented toward plastics and related applications where optical performance must be balanced with smooth processing. The product page highlights excellent whiteness and gloss, improved tint reducing power, easy dispersion, and good dry powder flowability, while describing weather and heat resistance as medium. For compounding operations, these attributes point to a grade intended to disperse efficiently and deliver a bright, opaque white without adding unnecessary viscosity or processing instability.
Applications listed include papermaking, masterbatch, plastic pipelines, and films. In paper systems, the pigment’s scattering power and stable dispersion contribute directly to brightness and opacity, and they can help reduce defects such as specking when coarse particles are controlled. In polymer masterbatch, dispersion quality determines how well the concentrate performs for downstream converters: better dispersion improves opacity at lower let-down rates and reduces the risk of streaking in films or visible specks in molded parts. For pipelines and films, stable shade and good gloss are important because surface defects and shade variation are highly visible on large or thin-wall products. In use, a consistent feeding strategy and adequate shear during compounding help the pigment reach its designed scattering efficiency.
The technical properties listed on the page provide a clearer picture of the grade’s balance. TiO2 content is ≥ 94.0% and rutile content is ≥ 98%. Optical indicators include L* ≥ 95.0 and light scattering power ≥ 100%. Cleanliness and handling indicators include residue (45 um) ≤ 0.05%, water soluble ≤ 0.3%, and volatiles at 105°C ≤ 0.5%. Processing-related values include pH (water suspension) 6.0–8.0, oil absorption ≤ 21 g/100 g, resistivity ≥ 80 ohm·m, and oil dispersity expressed as Hegmann value ≥ 6.0. Organic treatment is stated as yes. Taken together, the description and specifications position NR-930 as a plastic-friendly rutile TiO2 suitable for masterbatch and film/pipe applications where brightness and dispersion efficiency are important, and where “premium exterior” weathering is not the sole requirement.
