Description

Disperse Red 5 is a synthetic anthraquinone derivative dye widely used for its excellent color properties. This high-performance colorant is valued for its strong, bright red hue and good fastness characteristics in synthetic polymer systems. It is primarily utilized by manufacturers in the textile and plastics industries seeking reliable and consistent coloration. The product is supplied under strict quality control to ensure batch-to-batch uniformity for industrial applications.

Application

• Textile Dyeing: Primary application for dyeing hydrophobic fibers like polyester, acetate, and nylon, offering good wash and light fastness.
• Plastics Coloring: Used as a colorant for engineering plastics, polystyrene, ABS, and other synthetic polymers requiring a stable red shade.
• Ink Manufacturing: Suitable for formulating specialty inks, including inks for synthetic fabrics and transfer printing.
• Acrylic Fiber Dyeing: Employed in the coloration of modified acrylic fibers where disperse dyes are applicable.
• Research & Development: Serves as a reference standard or intermediate in chemical research and dye synthesis laboratories.

Quality Control

Our Disperse Red 5 is manufactured under a stringent quality management system to ensure it meets the high standards required for industrial dye applications. Every batch is tested for critical parameters including color strength, shade, particle size distribution, and dispersion stability. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and performance tests is available for each shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, prolonged exposure to direct light should be avoided to maintain product integrity.
