For professionals in the chemical and plastics industries, selecting the right colorants is a decision that impacts product performance, aesthetics, and market appeal. Solvent Orange 63, identified by CAS number 16294-75-0, is a highly regarded fluorescent dye that offers a compelling combination of vibrant color, excellent thermal stability, and broad application scope. This article delves into the key properties and applications that make Solvent Orange 63 a preferred choice for many manufacturers.

Solvent Orange 63 is characterized by its appearance as a fine orange powder. Its molecular formula is C23H12OS, with a molecular weight of 336.41. What distinguishes this dye is its superior heat resistance, typically rated at 300°C minimum, and a robust light fastness of 6-7. These attributes are crucial for B2B procurement managers and product formulators who need colorants that can withstand the rigors of plastic processing, such as extrusion and injection molding, without degradation or fading. The dye's high tinting strength also means a little goes a long way, contributing to cost-effectiveness.

When sourcing for industrial needs, finding a reliable manufacturer or supplier is critical. B2B buyers often prioritize suppliers who can guarantee consistent product quality, offer competitive prices, and ensure a stable supply chain. For Solvent Orange 63, especially when looking to buy in bulk, understanding the product's specifications and the supplier's capabilities is paramount. Many businesses look towards China for sourcing these types of specialty chemicals due to the competitive market and extensive manufacturing capabilities.

The primary application of Solvent Orange 63 lies in the coloration of various polymers and plastic products. Its excellent compatibility makes it suitable for a wide range of resins, including:

  • Polystyrene (PS): Ideal for consumer goods, packaging, and toys where bright, eye-catching colors are desired.
  • ABS Resin: Used in automotive interiors, electronic housings, and appliance components, requiring durable and stable coloration.
  • Polycarbonate (PC) & PMMA: For applications demanding high clarity and vibrant colors, such as lighting fixtures and display screens.
  • PET Fiber: Imparts bright, fluorescent shades to synthetic fibers used in textiles and apparel.
  • Other Plastics: Including SAN, AS, PA6, and RPVC, where specific color requirements need to be met.

The fluorescent nature of Solvent Orange 63 adds a distinct visual appeal, making products highly visible and attractive. This property is particularly advantageous for safety applications, signage, and high-fashion items.

For R&D scientists and product developers, understanding how to effectively incorporate Solvent Orange 63 is key. Its oil solubility ensures good dispersion in many plastic melts. When evaluating potential suppliers, requesting a sample and reviewing its technical data sheet (TDS) is a standard practice. This allows for laboratory testing to confirm its suitability for specific plastic formulations and processing parameters.

In summary, Solvent Orange 63 is an essential colorant for the plastics industry, offering a superior blend of vibrant color, fluorescence, and stability. By carefully selecting a reputable manufacturer and understanding its technical specifications, businesses can effectively enhance their plastic products and gain a competitive edge.
