CAS 169198-72-5: An Overview of UV Absorber UV-366
UV Absorber UV-366 is a highly effective benzotriazole-type UV absorber. Its chemical structure and molecular properties are engineered to provide superior protection against ultraviolet radiation, a primary cause of polymer and textile degradation. As a key component in many advanced formulations, understanding its unique attributes is essential for optimizing its application.

Key Technical Specifications and Advantages:

• Chemical Identity: The chemical name is 2-(2-hydroxy-4'-benzoyloxyphenyl)-5-chloro-benzotriazole. The CAS number 169198-72-5 is globally recognized for this specific compound.
• Appearance: It presents as a light yellow powder, ensuring it does not adversely affect the color of the materials it is incorporated into.
• Assay/Purity: Typically with an assay of 98.5% minimum, this indicates a high level of purity, critical for consistent performance in demanding applications.
• Melting Point: The melting point range of 183.00-185.00°C signifies its thermal stability during processing.
• High UV Absorption Efficiency: A standout feature is its significantly higher UV molar extinction coefficient compared to conventional UV absorbers like benzophenones and older benzotriazole derivatives. This translates directly to enhanced protection for polymers and fibers.
• High Molecular Weight & Non-Volatility: These characteristics prevent the loss of the additive during high-temperature processing or long-term use, ensuring sustained protection.
• Extraction Resistance: UV-366 is resistant to extraction, meaning it remains bound within the polymer matrix or textile fiber, providing long-lasting protection against environmental factors.
• Broad Compatibility: It is suitable for a wide range of polymers, including PP, PE, ABS, PVC, nylon, and polyurethane, and is especially effective for polyester fibers.
