Description

C.I. Disperse Red 43 is a synthetic anthraquinone-based dye belonging to the disperse dye class, widely recognized for its vibrant red hue. This product is engineered for exceptional color fastness and dispersion stability, making it a critical component for achieving durable and consistent coloration on synthetic fibers. It is primarily utilized by manufacturers in the textile industry, particularly for dyeing and printing polyester and acetate fabrics, as well as in specialized applications for plastics and inks.

Application

• Textile Dyeing: Primary application for dyeing polyester (PET), acetate, and triacetate fibers, offering excellent wash and light fastness.
• Textile Printing: Used in printing pastes for synthetic fabrics to create sharp, colorfast patterns.
• Plastics Coloring: Imparts a stable red color to various thermoplastic polymers, including polystyrene and polycarbonate.
• Ink Manufacturing: Serves as a colorant for specialty inks, including those for transfer printing and certain plastic substrates.
• Nylon Dyeing: Applicable for dyeing specific types of nylon fibers where disperse dyes are suitable.
• Research & Development: Used as a standard or reference material in analytical chemistry and dye research laboratories.
