Description

Direct Blending Navy Blue D-R CAS NO 72586-15-3 is a high-performance, direct blending dye designed for precise and consistent coloration in demanding industrial applications. Its primary value lies in its ability to deliver a stable and intense navy blue shade with excellent dispersion properties, ensuring uniform results and operational efficiency. This product is essential for manufacturers in the plastics, synthetic fibers, and masterbatch industries who require reliable, high-strength colorants for their polymer systems.

Application

• Plastics Coloring: Primary application for coloring polyolefins (PP, PE), polystyrene, ABS, and engineering plastics.
• Synthetic Fiber Production: Used in the spin-dyeing of polyester, nylon, and polypropylene fibers to achieve deep, fast navy blue hues.
• Masterbatch & Compound Manufacturing: A key component in the production of color concentrates and pre-colored compounds for downstream processing.
• Injection Molding and Extrusion: Provides consistent coloration for a wide range of molded and extruded plastic parts and films.
• Filament and Staple Fiber: Imparts excellent color fastness and thermal stability in textile and industrial yarn production.
• Technical Parts: Suitable for coloring automotive components, household appliances, and packaging materials where color consistency is critical.
