Rockwood Pigments 321T

Technical DataSheet | Supplied by Huntsman

A light tan ferrite, produced by the high temperature reaction of iron oxide and zinc oxide (Fe2O3•ZnO). Is a high performance, heat stable pigment, formulated for color consistency and stable performance in plastics and other high-heat applications where high temperature resistance and weather durability is required. Improves exterior durability by the ultraviolet screening properties contributed by these pigments, especially with polymers that are sensitive to sunlight. Provides various advantages like heat stability, color, dispersion, exterior durability, UV screening, Non-migration, bleed resistance, and quality assurance. Is inert, insoluble in organic materials, resistant against chemicals, alkali and dilute acids. Recommended, owing to its sufficient purity, for use in selected applications for packaging or articles that come in contact with food (21CFR). High temperature stability and ease of dispersion make these pigments suitable for resin systems from LLDPE and vinyl to sophisticated engineering polymers and silicone rubber compounds. Used in plastics.
