For R&D scientists and product formulators, selecting the right additives is critical for achieving desired material properties and performance. UV Absorber 326 (CAS No. 3896-11-5) is a highly effective light stabilizer that plays a crucial role in preventing UV-induced degradation in a wide range of polymers. Its technical profile makes it a favored choice for applications demanding superior weatherability and long-term stability. NINGBO INNO PHARMCHEM, a prominent UV Absorber 326 supplier in China, provides detailed technical insights for professionals seeking to optimize their formulations.

The core technical advantage of UV Absorber 326 is its broad absorption spectrum, effectively capturing ultraviolet radiation between 270 and 380 nm. This capability is vital for protecting polymers from chain scission, cross-linking, and the generation of chromophores, all of which lead to material degradation. Its chemical structure, a hydroxyphenylbenzotriazole derivative, allows for efficient energy dissipation as heat, minimizing photochemical damage. When you buy UV Absorber 326, you are investing in a product known for its low volatility and excellent thermal stability, allowing it to withstand processing temperatures common in polymer manufacturing without significant decomposition.

Formulators often rely on the UV Absorber 326 datasheet to understand its compatibility and optimal incorporation levels. Typically, recommended usage levels range from 0.05% to 0.5% by weight, depending on the polymer type, product thickness, and intended exposure conditions. Its compatibility with polyolefins, PVC, polycarbonate, and unsaturated polyesters is well-documented. For instance, in polyester resins, it avoids forming colored complexes with metallic curing agents, a distinct advantage over some other UV absorbers. Understanding competitive UV absorber pricing from a reliable manufacturer like NINGBO INNO PHARMCHEM ensures that performance enhancements do not come at an prohibitive cost.

The ability of UV Absorber 326 to absorb UV light with minimal impact on visible light transmission makes it particularly valuable for transparent and lightly colored applications. This includes clear coatings, films, and molded parts where maintaining aesthetic appeal is as important as durability. As a dedicated chemical supplier, NINGBO INNO PHARMCHEM is committed to providing technical support to help formulators leverage the full benefits of UV Absorber 326, ensuring robust UV protection and enhanced product performance.
