Description

Disperse Blue 82 is a high-performance anthraquinone-based dye renowned for its excellent color fastness and dispersion properties. It is a critical component for achieving deep, vibrant blue shades with superior wash and light resistance in synthetic textiles. This product is essential for manufacturers in the polyester and acetate fiber industries seeking reliable and consistent coloration. Its stability makes it a preferred choice for demanding dyeing applications where color integrity is paramount.

Application

• Primary dyeing of polyester fibers and fabrics (textile, apparel, home furnishings).
• Dyeing of acetate fibers for specialized textile applications.
• Coloration of polyamide (nylon) fibers, often in combination with other dyes.
• Use in the mass coloration of synthetic polymers during the spinning process.
• Manufacture of inks and toners for specialized printing applications.
• Production of colored plastics and masterbatches where high-temperature stability is required.
