Description

Disperse Orange 50 is a synthetic organic dye belonging to the disperse dye class, widely used for its excellent colorfastness properties. This high-performance dye is engineered to provide vibrant and durable coloration on synthetic hydrophobic fibers. It is a critical component for manufacturers in the textile and plastics industries seeking reliable and consistent orange hues. The product is supplied as a fine powder, ensuring optimal dispersion and solubility in application baths.

Application

• Textile Dyeing: Primary application for dyeing polyester (PET), acetate, and triacetate fibers, offering excellent wash and light fastness.
• Plastics Coloring: Used for mass coloration of engineering plastics, polystyrene, and other synthetic polymers.
• Ink Manufacturing: A key pigment for specialty inks, including those for transfer printing and synthetic material marking.
• Automotive Interiors: Employed in dyeing polyester-based fabrics and components used in vehicle upholstery and trim.
• Sportswear and Outdoor Gear: Ideal for synthetic fabrics requiring bright, fade-resistant colors under demanding conditions.
• Non-Woven Fabrics: Used in the coloration of polyester-based non-woven materials for various industrial and consumer products.
