For many industries, protecting materials from the detrimental effects of ultraviolet (UV) radiation is a critical aspect of product development and manufacturing. UV Absorber UV-P (CAS No. 2440-22-4) is a highly effective additive that provides robust UV protection for a wide array of polymers. As a direct manufacturer and supplier, understanding the quality parameters and application nuances of UV-P is central to our mission of serving B2B clients effectively.

The Science Behind UV-P's Protection

UV-P is a benzotriazole-based UV absorber. Its molecular structure is engineered to efficiently capture UV radiation within the 290-400 nm range, a spectrum particularly damaging to organic materials. Upon absorbing UV photons, the molecule undergoes a rapid internal conversion process, dissipating the energy as heat. This cycle can repeat numerous times, providing long-lasting protection without significant degradation of the absorber itself. A key characteristic that makes UV-P highly sought after by formulators and procurement specialists is its minimal absorption in the visible light spectrum. This ensures that the optical clarity and inherent color of the polymer or coating remain unaltered, a crucial advantage for applications like clear films, transparent coatings, and aesthetic components.

Critical Quality Specifications for Buyers

As a manufacturer, we focus on producing UV-P that meets stringent quality benchmarks. For procurement managers and R&D scientists, these specifications are vital for ensuring performance and reliability:

  • Appearance: Typically described as a white to light yellow powder, indicating purity and consistent physical form.
  • Assay (Purity): A high assay, usually ≥99.0%, ensures that the active ingredient is present in sufficient concentration for effective UV absorption. We employ advanced analytical techniques to guarantee this level of purity.
  • Transmittance: High transmittance at specific wavelengths (e.g., 440nm > 97%, 550nm > 98%) is critical for applications demanding optical clarity. This parameter directly correlates to the product's suitability for clear applications.
  • Melting Point: A defined melting point range (e.g., 125.5-129.5 °C) indicates the product's consistency and purity.
  • Ash Content: Low ash content (≤0.20%) signifies minimal inorganic impurities, which is important for sensitive applications.

We understand that purchasing chemical raw materials involves a high degree of trust. Our role as a direct manufacturer allows us to control the production process from start to finish, guaranteeing that every batch of UV-P we supply adheres to these critical quality standards.
