In the dynamic world of polymer manufacturing, safeguarding materials against the relentless assault of ultraviolet (UV) radiation is paramount. UV degradation can lead to a cascade of issues, including discoloration, embrittlement, cracking, and a significant loss of mechanical properties. This is where advanced UV absorbers, such as UV Absorber 326, play a critical role. As a leading manufacturer and supplier of specialty chemicals, we understand the challenges faced by product formulators and are dedicated to providing solutions that enhance material performance and longevity.

UV Absorber 326, belonging to the benzotriazole class, is a highly effective light stabilizer. Its primary function is to absorb harmful UV radiation, particularly in the 300-400nm range, and dissipate this energy as heat. This mechanism prevents the UV energy from initiating photo-oxidative degradation processes within the polymer matrix. The chemical structure of UV Absorber 326 (2-(2'-hydroxy-3'-tert-butyl-5'-methylphenyl)-5-chlorobenzotriazole) is specifically designed for high efficiency and stability.

One of the key advantages of UV Absorber 326 is its excellent compatibility with a wide range of polymers, including polyolefins (like polyethylene and polypropylene), PVC, ABS, polycarbonates, and polyesters. This broad compatibility makes it a versatile choice for manufacturers across various sectors. Furthermore, its low volatility and high resistance to thermal degradation ensure that it remains effective even during high-temperature processing and molding stages, minimizing loss and decomposition.

The applications for UV Absorber 326 are extensive. In the plastics industry, it is vital for improving the weatherability and color stability of products intended for outdoor use, such as automotive parts, construction materials, and agricultural films. For coatings and paints, it helps prevent fading, chalking, and delamination, extending the aesthetic appeal and protective functions of surfaces. The adhesive and sealant sectors also benefit from its ability to maintain integrity under UV exposure.

For purchasing professionals and R&D scientists, sourcing a reliable supplier is crucial. When you seek to buy UV Absorber 326, consider partnering with established manufacturers in China who can guarantee product quality, consistent supply, and competitive pricing. Understanding the CAS number (3896-11-5) and chemical name is essential for accurate procurement. Many suppliers offer competitive UV Absorber 326 prices, making it an accessible solution for enhancing product durability.

Choosing the right UV absorber involves considering the specific polymer system, intended application, and environmental exposure. UV Absorber 326 stands out due to its proven efficacy, good compatibility, and approvals for indirect food contact in certain applications. By incorporating this advanced UV absorber into your formulations, you can significantly improve product lifespan and performance, meeting the growing demands for durable and weather-resistant materials.
