NINGBO INNO PHARMCHEM CO.,LTD. is pleased to announce the availability of its high-quality UV Absorber 531, also known chemically as 2-hydroxy-4-octoxy-benzophenone, with CAS No. 1843-05-6. This product stands as a cornerstone in the realm of material protection, serving as a highly effective ultraviolet absorber and light stabilizer crucial for extending the lifespan and maintaining the aesthetic integrity of various materials subjected to UV radiation.

Exposure to ultraviolet light from the sun or artificial sources can cause significant degradation in polymers, coatings, and rubber products. This degradation manifests as color fading, loss of gloss, chalking, cracking, and a reduction in mechanical strength. UV absorbers like UV Absorber 531 function by absorbing harmful UV radiation and dissipating it as harmless thermal energy, thereby shielding the protected material from photo-oxidative damage. This protective mechanism is vital for applications intended for outdoor use or those exposed to intense indoor lighting conditions.

Our UV Absorber 531 is a finely processed powder, typically presenting a slight yellow appearance. It boasts a high level of purity, consistently meeting or exceeding 99%. Key physical and chemical properties make it particularly suitable for demanding applications. It features a low volatile matter content, indicating its stability and minimal loss during high-temperature processing. The melting point falls within the range of 47 to 50ºC, facilitating its incorporation into various matrices. Furthermore, its light transmittance is excellent, particularly at higher wavelengths, confirming its effectiveness in absorbing UV light while minimally impacting visible light transmission, a critical factor for clear or lightly colored applications.

One of the standout characteristics of NINGBO INNO PHARMCHEM's UV Absorber 531 is its low volatility and resistance to migration. These properties ensure that the additive remains within the material over time and under various environmental stresses, providing long-lasting protection. Unlike volatile or migratory additives that can deplete from the surface, leaving the material vulnerable, UV Absorber 531 offers sustained performance throughout the product's service life. Its easy processing properties further enhance its appeal, allowing for smooth and efficient incorporation into polymer melts, coating formulations, and rubber compounds using standard manufacturing techniques.

The product exhibits excellent solubility and compatibility with a wide range of polymers and solvent-based systems, including high-solid coatings formulations. This broad compatibility is essential for achieving uniform distribution of the additive within the host material, ensuring consistent protection throughout the entire cross-section. UV Absorber 531 also demonstrates an excellent synergistic effect when used in combination with antioxidants and other light stabilizers, allowing for enhanced protection and potential cost optimization by leveraging the combined power of different additive types.

The applications of UV Absorber 531 from NINGBO INNO PHARMCHEM CO.,LTD. are extensive and diverse. It is widely recommended for use in polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP), polystyrene (PS), polycarbonate (PC), ethylene-vinyl acetate (EVA), and polymethyl methacrylate (plexiglass). In the coatings industry, it is highly effective in automotive paints, powder coatings, and polyurethane systems, where maintaining color fastness and gloss under sunlight is paramount. Its utility also extends to various rubber products, where UV exposure can lead to cracking and embrittlement.
