The durability and aesthetic appeal of polymer-based products are significantly challenged by exposure to ultraviolet radiation. This ubiquitous environmental factor initiates photochemical reactions that can break down polymer chains, leading to brittleness, discoloration, and a drastic reduction in functional lifespan. For procurement managers and product developers, identifying and sourcing effective UV stabilizers is a strategic imperative. From our position as a premier manufacturer and supplier of specialty chemicals in China, we understand the critical need for high-performance additives that deliver reliable protection. Our offering of 2-(2'-Hydroxy-4'-benzoyloxyphenyl)-5-chlorobenzotriazole (CAS 169198-72-5), known commercially as UV-366, addresses this challenge directly.

UV-366 is a sophisticated benzotriazole UV absorber engineered for maximum efficacy. Its molecular structure is designed to efficiently absorb harmful UV light across a broad spectrum, preventing it from reaching and degrading the polymer matrix. Unlike lower molecular weight UV absorbers, UV-366 boasts a high molecular weight, which translates into significantly reduced volatility and excellent resistance to extraction. This means that once incorporated into a polymer, the UV protection remains robust, even when the material is subjected to washing, exposure to solvents, or high processing temperatures. For businesses looking to buy chemical raw materials that guarantee sustained performance, UV-366 is an outstanding choice.

The advantages this UV absorber brings to plastic manufacturing are manifold. Its superior UV absorption efficiency, evidenced by its high molar extinction coefficient, ensures that even relatively low concentrations can provide substantial protection. This makes it a cost-effective solution for achieving high-grade results. Furthermore, its physical form – a light yellow powder – ensures that it does not impart undesirable color or opacity to the final product, allowing the original aesthetics of the plastic to shine through. For R&D scientists and formulators, purchasing UV-366 from a trusted China supplier ensures access to consistent quality and the technical support needed for optimal integration.

The applications for UV-366 are extensive, covering a wide range of polymers critical to modern industry. It is particularly effective in polyolefins (PP, PE), polystyrene, ABS resins, PVC, nylon, and polyurethanes. These materials are used in everything from automotive components and outdoor furniture to packaging films and electronic housings, all of which benefit greatly from enhanced UV resistance. By choosing to buy this advanced UV stabilizer, manufacturers can significantly extend the service life of their products, reduce warranty claims, and improve customer satisfaction. We, as a leading chemical supplier in China, are proud to offer this solution to meet global demand.
