Solvent Red 23 (CAS 85-86-9) stands out as a highly effective and versatile solvent dye, particularly favored in the plastics and polymer industry for its ability to impart a brilliant, transparent red hue. As a product manufactured and supplied by leading chemical companies, understanding its properties and applications is key for product formulators and procurement managers seeking high-performance colorants.

The Chemistry of Color: Solvent Red 23 Properties

Chemically classified as a diazo compound, Solvent Red 23 is characterized by its excellent solubility in organic solvents and nonpolar substances, a trait that makes it ideal for incorporation into plastic matrices. Its molecular formula is C22H16N4O, with a molecular weight of approximately 352.39 g/mol. The dye typically presents as a yellowish-red powder. Crucially for industrial use, it exhibits good heat resistance, often withstanding temperatures around 260°C, and possesses good lightfastness, ensuring the longevity of the color in finished plastic products.

Key Applications in Polymer Processing

The primary application of Solvent Red 23 lies in the coloration of various plastics and polymers. Its transparency and bright red shade are highly sought after in applications where visual appeal is critical. Some of the most common polymers colored with Solvent Red 23 include:

  • Polymethyl Methacrylate (PMMA): Often used in transparent acrylic products, where the dye imparts a crystal-clear red color.
  • Acrylonitrile Butadiene Styrene (ABS) Resin: Provides a vibrant red for consumer goods, automotive parts, and electronic casings.
  • Polyvinyl Chloride (PVC): Used in both rigid and flexible PVC applications, such as pipes, profiles, and films.
  • Styrene-Acrylonitrile (SAN) and Acrylonitrile Styrene Acrylate (ASA) resins: Enhances the aesthetic appeal of housewares and appliance components.

Beyond these polymers, Solvent Red 23 also finds applications in coloring greases, waxes, petroleum products, and even in certain ink formulations for ballpoint pens due to its inherent solvency.

Procurement and Sourcing of Solvent Red 23

For businesses looking to purchase Solvent Red 23, identifying reliable manufacturers and suppliers is essential. Many leading chemical companies, particularly in China, offer this dye with high purity and consistent quality. When you seek to buy Solvent Red 23, consider engaging with suppliers who can provide detailed product specifications, batch analysis reports, and responsive customer service. They can guide you on the optimal dosage for your specific polymer and processing conditions, ensuring the best color yield and performance. Partnering with a trusted manufacturer ensures not only product quality but also a stable supply chain, crucial for uninterrupted production.

In summary, Solvent Red 23 is an indispensable colorant for the plastics and polymer industry. Its unique properties and broad applicability make it a valuable asset for manufacturers aiming to achieve vibrant, durable red coloration in their products. We recommend consulting with experienced suppliers to ensure you source high-quality Solvent Red 23 that meets all your application requirements.
