Carbon Black C-391 by Huntsman is fluffy-grade carbon black pigment used in plastics. Possesses a blue tone, relatively low oil absorption, easy dispersibility and very good coloring or tinting vs. lampblack and a very high jetness index relative to other carbon blacks and is conductive to electricity. Exhibits stability to sunlight and UV radiation, and resistance to alkali. Does not contain any calcium sulfate. Complies with specifications: TT-L-70, TT-P-350 and NBS Color 318. Recommended, owing to its sufficient purity, for use in articles that come in contact with food (21CFR), but not suitable for the direct coloration of pet food or cosmetics. Carbon Black C-391 is used for plastics and rubbers applications.
