Description

Disperse Blue 27 is a synthetic anthraquinone derivative dye widely recognized for its excellent color fastness and dispersion properties. This high-performance dye is engineered to deliver consistent, vibrant blue shades with superior thermal stability, making it a critical component in demanding coloration processes. It is primarily utilized by manufacturers in the textile and plastics industries seeking reliable and efficient coloring solutions for synthetic fibers and polymers.

Application

• Primary dyeing and printing of hydrophobic synthetic fibers such as polyester and acetate.
• Coloration of polyamide (nylon) fibers, often requiring specific pH control.
• Mass pigmentation or spin-dyeing of plastics and synthetic resins, including polycarbonate and ABS.
• Manufacturing of transfer papers for sublimation printing applications.
• Production of colored masterbatches for consistent color delivery in polymer processing.
• Specialized applications in the coloring of automotive textiles and interior fabrics requiring high lightfastness.
