In the competitive world of material science and manufacturing, extending the lifespan and preserving the aesthetic qualities of polymer-based products is paramount. Exposure to ultraviolet (UV) radiation from sunlight is a primary cause of polymer degradation, leading to discoloration, loss of mechanical strength, and surface deterioration. Fortunately, advanced chemical solutions like UV absorbers are readily available to combat these effects. Among these, UV Absorber UV-328 (CAS: 25973-55-1) stands out as a highly effective and versatile additive. As a leading manufacturer and supplier of this crucial chemical, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing superior polymer protection solutions.

UV Absorber UV-328 is a benzotriazole derivative renowned for its ability to efficiently absorb UV light within the critical 270-340 nm wavelength range. This absorption mechanism converts harmful UV energy into harmless thermal energy, preventing it from initiating degradation reactions within the polymer matrix. Its excellent compatibility with a wide range of polymers, including polyolefins (such as polyethylene and polypropylene), polyesters, styrenic polymers, polyamides, PVC, and polyurethanes, makes it a highly sought-after product for various industrial applications.

What sets UV-328 apart is its combination of high UV absorption efficiency with desirable physical properties. It exhibits low volatility, meaning it remains within the polymer matrix even at elevated processing temperatures, ensuring long-term protection. Furthermore, its high washing resistance guarantees that the UV protection is not easily leached out by water or cleaning agents. This makes it an ideal choice for products intended for outdoor use or those requiring repeated cleaning. For procurement professionals and formulators seeking reliable polymer additives, understanding the benefits and sourcing options is key. As a dedicated manufacturer and supplier based in China, we offer competitive pricing for UV Absorber UV-328, ensuring that businesses can access high-quality materials without compromising on cost-effectiveness.
