Description

Disperse Blue 3 is a synthetic anthraquinone derivative dye widely recognized for its vibrant blue hue and excellent colorfastness properties. This product is essential for achieving deep, consistent coloration in synthetic hydrophobic fibers where traditional dyes are ineffective. It is primarily utilized by manufacturers in the textile and plastics industries seeking reliable and durable colorants for their polyester, acetate, and nylon products. Our supply of Disperse Blue 3 CAS NO 2475-46-9 is backed by stringent quality control to ensure batch-to-batch consistency for industrial applications.

Application

• Primary dyeing and printing of polyester fibers and fabrics.
• Coloration of acetate and triacetate textiles.
• Dyeing of nylon and other synthetic fibers.
• Mass coloration of plastics and resins, including polystyrene and polycarbonate.
• Manufacture of transfer papers for sublimation printing.
• Production of inks for specialized printing applications.
• As a colorant in the research and development of new polymeric materials.
