As a manufacturer, selecting the right UV absorber is critical for ensuring the longevity and performance of your plastic and coating products. Ultraviolet (UV) radiation from sunlight can cause significant degradation, leading to discoloration, loss of mechanical properties, and reduced service life. This guide, presented by NINGBO INNO PHARMCHEM CO.,LTD., will help you navigate the complexities of choosing the best UV absorber for your specific needs.

Understanding UV Degradation

UV degradation, or photodegradation, occurs when UV light energy breaks down the chemical bonds within polymers and coatings. This process can manifest as fading, chalking, cracking, and a general deterioration of the material's physical properties. Effectively combating this requires the strategic use of UV stabilizers, with UV absorbers being a primary line of defense.

Key Factors When Selecting a UV Absorber:

  • Absorption Spectrum: Different UV absorbers have varying absorption ranges. It's crucial to choose one that effectively covers the wavelengths most damaging to your specific substrate. For instance, absorbers like CI 46025 (CAS 135-49-9) offer broad-spectrum protection, making them versatile for many applications. As a trusted manufacturer, we ensure our UV absorbers provide optimal absorption to meet your protection needs.
  • Compatibility with Substrate: The UV absorber must be compatible with the polymer or coating formulation. Incompatibility can lead to blooming, reduced effectiveness, or processing issues. Consider solubility in common solvents and resins when making your selection. We offer high-quality UV absorbers that are compatible with a wide range of industrial materials.
  • Thermal Stability: Many manufacturing processes involve high temperatures. The UV absorber must withstand these conditions without decomposing or losing its efficacy. This is a crucial parameter for reliable performance, and as a leading supplier, we ensure our products meet stringent thermal stability requirements.
  • Light Fastness and Photostability: A good UV absorber should not only absorb UV light but also remain stable under prolonged UV exposure itself. This ensures long-term protection for your products. Enquire about our UV absorber price and performance data to make an informed decision.
  • Regulatory Compliance and Safety: Ensure the UV absorber meets all relevant safety and regulatory standards for your intended application, especially for food contact or cosmetic uses.
