In the realm of industrial colorants, Solvent Yellow 93, also known as Transparent Yellow 3G (C.I. Solvent Yellow 93), stands out for its exceptional performance and versatility. This yellow powder dye, with its characteristic greenish-yellow hue, finds extensive application across various sectors, primarily in the coloration of plastics and polyester fibers. For businesses seeking reliable and high-quality sourcing, understanding its properties and the advantages of purchasing from specialized manufacturers in China is crucial.

Chemical Profile and Key Performance Indicators

Solvent Yellow 93 (CAS No. 4702-90-3) is a synthetic organic compound valued for its purity, typically boasting an assay of 99% or higher. Its molecular formula is C21H18N4O2, with a molecular weight of approximately 358.39 g/mol. The dye presents as a fine yellow powder, which ensures good dispersibility in various media.

The performance attributes that make Solvent Yellow 93 highly sought after include:

  • Heat Resistance: It exhibits excellent thermal stability, often rated up to 300°C. This allows it to withstand the high temperatures encountered during the processing of polymers like ABS, PC, and PET without significant degradation or color change.
  • Lightfastness: With a lightfastness rating of grade 7-8 on a scale of 1 to 8, it offers superior resistance to fading upon exposure to light, ensuring the longevity of colored products.
  • Solubility: It is insoluble in water but readily dissolves in various organic solvents such as ethanol, acetone, toluene, and dichloromethane, facilitating its use in solvent-based systems.
  • Dyeing Power: Solvent Yellow 93 offers strong tinting strength, meaning a small quantity can effectively color a larger volume of material, contributing to cost-efficiency.

For procurement managers and R&D scientists, understanding these specifications is key to determining the suitability of Solvent Yellow 93 for their specific applications. When you buy Solvent Yellow 93, you are investing in a colorant that promises vibrant, durable coloration.

Diverse Applications Across Industries

The primary applications for Solvent Yellow 93 include:

  • Plastic Coloration: It is widely used to color a broad spectrum of plastics, including PS, HIPS, ABS, PC, PMMA, SAN, AS, PET, and PVC-U. Its good migration resistance is also a critical factor in plastic applications.
  • Polyester Fiber: It is specifically employed for coloring the original pulp of polyester fibers, contributing to the vibrant hues seen in many textile products.
  • Masterbatch Production: Used in the manufacturing of masterbatches for coloring polyester and other plastics, offering ease of handling and consistent results.
