In the world of material science and manufacturing, preserving the integrity and aesthetic appeal of plastic products is paramount. Exposure to ultraviolet (UV) radiation from sunlight is a primary culprit behind the degradation of polymers, leading to discoloration, brittleness, and loss of mechanical properties. This is where the critical role of UV absorbers comes into play. As a leading manufacturer of specialty chemicals, we understand the importance of providing solutions that enhance product longevity. This article delves into the benefits and applications of UV Absorber UV-328, a high-performance additive that offers exceptional protection.

UV Absorber UV-328, chemically known as 2-(2H-benzotriazol-2-yl)-4,6-di-tert-pentylphenol (CAS No. 25973-55-1), is a highly effective UV absorber with a maximum absorption peak at 345nm. Its efficacy in preventing UV-induced damage makes it an indispensable component in various plastic formulations. Its excellent compatibility with a wide range of polymers, including polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), polyesters, and ABS resins, ensures seamless integration into your manufacturing processes. Furthermore, its low volatility and high wash resistance contribute to its superior performance, ensuring that your products maintain their protective qualities even under demanding environmental conditions.

For manufacturers seeking to improve the durability of their plastic goods, understanding the properties of UV Absorber UV-328 is key. Typically used at around 1% dosage, this UV stabilizer offers a significant uplift in material performance. Its ability to absorb harmful UV radiation effectively shields the polymer matrix from photo-oxidative degradation, thereby extending the service life of the end product. This is particularly crucial for items intended for outdoor use, where constant exposure to sunlight necessitates robust protection.
