For procurement managers, R&D scientists, and product formulators in the chemical and material industries, understanding the nuances of specialty chemicals is vital for making informed purchasing decisions. Among these critical additives, UV absorbers play a pivotal role in protecting materials from the detrimental effects of ultraviolet radiation. This guide aims to demystify a leading product in this category: 2-(2'-Hydroxy-4'-benzoyloxyphenyl)-5-chlorobenzotriazole, commonly known by its CAS number 169198-72-5 and commercial names like UV-366. As a dedicated manufacturer and supplier of high-quality chemical intermediates from China, NINGBO INNO PHARMCHEM CO.,LTD. provides insights into why this compound is a top choice for demanding applications.

The fundamental function of a UV absorber is to intercept and dissipate UV radiation before it can initiate degradation processes in the host material. UV-366 excels in this regard due to its advanced benzotriazole structure, which provides a broad absorption spectrum and high efficiency. This means it can effectively shield polymers, plastics, textiles, and coatings from UV-induced damage, such as discoloration, brittleness, and loss of mechanical strength. For businesses looking to buy chemical raw materials that promise enhanced product longevity, UV-366 is an indispensable ingredient.

What makes UV-366 particularly attractive to buyers is its exceptional profile of properties. Firstly, its high molecular weight and chemical stability make it non-volatile and resistant to extraction. This is crucial for applications where the material is exposed to solvents, high temperatures, or repeated washing, ensuring that the protective capabilities of the UV absorber are not compromised over time. Secondly, its performance in preventing photodegradation is superior to many conventional UV absorbers, offering a higher level of protection with potentially lower dosage requirements. Thirdly, it is supplied as a light yellow powder, which is generally compatible with most polymer systems without causing undesirable coloration. For procurement specialists, securing a reliable supply of this high-purity chemical from a trusted China manufacturer like ourselves is a strategic advantage.

The versatility of UV-366 is evident in its wide range of applications. It is extensively used in the stabilization of plastics like polypropylene (PP), polyethylene (PE), polystyrene, ABS, PVC, nylon, and polyurethanes. In the textile industry, it enhances the UV resistance and durability of fabrics, especially polyester fibers. It is also a vital component in high-performance coatings, protecting automotive finishes, industrial paints, and architectural coatings from weathering and UV damage. For any formulator seeking to buy chemical additives that deliver long-term performance and aesthetic preservation, UV-366 is a premier solution.
