In the relentless battle against environmental degradation, polymer manufacturers continuously seek additives that can extend the lifespan and maintain the aesthetic integrity of their products. Ultraviolet (UV) radiation from sunlight is a primary culprit, causing polymers to yellow, become brittle, and lose their essential mechanical properties. This is where the critical role of UV absorbers, particularly those within the benzotriazole class, comes into play. As a leading supplier of high-quality chemical additives, NINGBO INNO PHARMCHEM CO.,LTD. offers solutions like UV Absorber 329 (CAS: 3147-75-9) that provide unparalleled protection.

UV Absorber 329 is a high-efficiency benzotriazole-type UV absorber. Its core function is to absorb harmful UV radiation, specifically in the range of 270 to 380 nm, while crucially, not absorbing visible light. This characteristic makes it an indispensable component for transparent applications where maintaining clarity is paramount. Whether you are formulating for polycarbonate (PC), polyesters (PET), polyvinyl chloride (PVC), acrylics, or styrenics, this additive ensures that your products retain their original appearance and physical integrity, even when exposed to prolonged outdoor weathering.

One of the significant advantages of sourcing UV Absorber 329 from NINGBO INNO PHARMCHEM CO.,LTD. is its low volatility. This property is particularly beneficial for manufacturers working with engineering plastics that undergo high-temperature processing. The low volatility ensures minimal loss of the additive during extrusion or molding, leading to consistent and reliable product performance. This not only translates to better end-product quality but also to more efficient manufacturing processes, reducing waste and improving cost-effectiveness. We encourage procurement managers to consider our competitive bulk purchase pricing.

Furthermore, UV Absorber 329 exhibits excellent photo-permanence. This means that the additive itself is resistant to degradation by UV light, allowing it to provide sustained protection over an extended period. This long-term efficacy is vital for products intended for outdoor use, such as automotive components, building materials, and outdoor furniture. By incorporating this UV absorber, you are investing in the longevity and durability of your polymer formulations. Many of our clients in China and globally rely on us for these high-performance solutions.

The versatility of UV Absorber 329 is further highlighted by its ability to be used alone or in synergy with other stabilizers, such as hindered amine light stabilizers (HALS) and antioxidants. This synergistic approach can optimize performance, offering even greater protection and extending the service life of the polymer. For R&D scientists and product formulators, understanding these combinations can unlock new levels of product performance. We invite you to buy this essential additive from a trusted manufacturer and supplier.
