The plastics industry constantly seeks to improve the performance and lifespan of its products, especially when they are destined for outdoor use or applications involving significant light exposure. Ultraviolet (UV) radiation poses a constant threat, leading to material degradation. This is where chemicals like 2-(2′-hydroxy-3′,5′-dipentylphenyl)benzotriazole, identified by CAS number 21615-49-6, become indispensable.

CAS 21615-49-6 is a high-performance UV absorber belonging to the hydroxyphenylbenzotriazole class. Its unique molecular structure allows it to efficiently absorb UV radiation, particularly in the UV-A and UV-B regions, and convert it into heat. This process effectively shields polymers from the damaging effects of sunlight, preventing issues such as embrittlement, chalking, and discoloration. Its efficacy makes it a sought-after additive for a wide array of plastics, including polyolefins (like polyethylene and polypropylene), polyvinyl chloride (PVC), styrenic polymers (like polystyrene and ABS), polyesters, and polycarbonates.

As a light yellow powder, this UV absorber exhibits excellent compatibility with these diverse polymer matrices. Furthermore, its low volatility means it remains within the plastic matrix during high-temperature processing, and its inherent thermal stability ensures it doesn't degrade under typical manufacturing conditions. This makes it a reliable choice for manufacturers looking to enhance the durability and aesthetic appeal of their plastic products.
