For B2B procurement managers and product formulators in the plastics industry, selecting the correct colorant is paramount. Beyond aesthetics, the chosen dye must integrate seamlessly into manufacturing processes, maintain color integrity under various conditions, and comply with industry standards. Among the spectrum of available colorants, fluorescent dyes offer a unique vibrancy that can elevate product appeal. One such essential compound is Solvent Green 5 (CAS 2744-50-5), a high-performance fluorescent yellow dye widely sought after by plastic manufacturers worldwide.

Understanding Solvent Green 5: Properties and Advantages

Solvent Green 5, also known by synonyms like Fluorescent Yellow 8G, is a perylene-based dye characterized by its exceptional properties. As a solvent dye, it is designed to dissolve in specific media rather than disperse as solid particles. Its key attributes include:

  • High Transparency: Unlike pigments, solvent dyes offer excellent transparency, which is critical for applications like clear or translucent plastic components.
  • Superior Heat Stability: With a reported temperature resistance of up to 280-300°C, Solvent Green 5 is ideal for demanding extrusion and injection molding processes where plastics are subjected to high temperatures. This robust heat resistance ensures the dye does not degrade, ensuring consistent color output.
  • Excellent Lightfastness: Rated highly for light resistance (grades 7-8), this dye maintains its vibrant hue even when exposed to sunlight or other light sources over extended periods, preventing premature fading.
  • Vibrant Fluorescent Yellow Hue: Its signature bright, fluorescent yellow color provides a visually striking appearance, making products stand out in the market.
  • Broad Solubility: While insoluble in water, Solvent Green 5 exhibits good solubility in various organic solvents, including toluene, dichloromethane, and butyl acetate, facilitating its incorporation into different plastic matrices.

Applications in the Plastics Industry

The versatility of Solvent Green 5 makes it a preferred choice for a wide array of plastic applications. It is extensively used for coloring rigid plastic materials such as:

  • Polystyrene (PS) and High Impact Polystyrene (HIPS)
  • Acrylonitrile Butadiene Styrene (ABS)
  • Polycarbonate (PC)
  • Polyvinyl Chloride (PVC)
  • Polymethyl Methacrylate (PMMA)
  • Polyethylene Terephthalate (PET) and Polybutylene Terephthalate (PBT)
  • Styrene Acrylonitrile (SAN) and Acrylonitrile Styrene Acrylate (ASA)

Its ability to provide bright, transparent, and durable coloration makes it suitable for consumer goods, packaging, automotive components, and more. When seeking to buy Solvent Green 5 for your plastic manufacturing needs, sourcing from a reliable manufacturer and supplier in China is often the most cost-effective strategy.

Procurement Considerations: Finding a Reliable Supplier

When evaluating potential suppliers for Solvent Green 5, B2B buyers should prioritize factors such as purity, consistency, lead times, and pricing. A reputable supplier will offer detailed technical data sheets (TDS) and certificates of analysis (CoA) confirming the dye's specifications, including its CAS number (2744-50-5) and molecular formula (C30H28O4). Engaging with a supplier that offers competitive Solvent Green 5 price points for bulk purchases can significantly impact your overall production costs.
