Description

Disperse Yellow 50 is a high-performance synthetic organic dye belonging to the disperse dye class, widely recognized for its vibrant yellow hue. It is essential for achieving consistent, wash-fast, and light-fast coloration on synthetic hydrophobic fibers. This product is a critical raw material for manufacturers in the textile and polymer industries seeking reliable and efficient dyeing solutions. Its specific properties make it suitable for specialized applications requiring durable color under demanding conditions.

Application

Disperse Yellow 50 is primarily used for dyeing and printing synthetic fibers. Its key applications include:

• Textile Dyeing: Primary application for dyeing polyester (PET), acetate, and triacetate fibers, as well as their blends, in various forms (yarn, fabric, garments).
• Textile Printing: Used in printing inks for synthetic fabrics to create sharp, defined patterns.
• Plastics and Polymers: Coloring of plastics like polystyrene, polycarbonate, and certain nylons where thermal stability is required.
• Specialty Inks: Formulation of inks for transfer printing and other specialty marking applications.
• Research & Development: Serves as a standard or intermediate in chemical research and quality control laboratories.

Quality Control

Our Disperse Yellow 50 is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for color strength, shade, and chemical purity. Certificates of Analysis (COA) documenting key parameters such as purity, ash content, and dispersion stability are available upon request. We adhere to industry-standard testing protocols to guarantee batch-to-batch consistency and performance reliability for our global customers.

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.
