Description

Disperse Yellow 182 is a high-performance synthetic organic dye belonging to the disperse dye class, identified by CAS No. 112487-20-4. It is engineered to deliver excellent color fastness, brightness, and dispersion stability, which are critical for achieving consistent and vibrant coloration in synthetic materials. This product is essential for manufacturers in the textile and polymer industries who require reliable and efficient dyes for hydrophobic fibers.

Application

• Primary dyeing of polyester (PET) fibers and fabrics for apparel and home textiles.
• Coloration of polyamide (nylon) materials, including automotive and industrial fabrics.
• Printing applications on synthetic textiles using various techniques like heat transfer printing.
• Mass coloration (dope dyeing) of polyester chips during polymer synthesis for superior color consistency.
• Dyeing of acetate and other synthetic fibers in blend fabrics.
• Potential use in coloring certain plastics and specialty polymers.
