In the world of polymer science, extending the lifespan and maintaining the aesthetic integrity of plastic products is a paramount concern. Ultraviolet (UV) radiation from sunlight is a primary culprit behind polymer degradation, leading to discoloration, embrittlement, and loss of mechanical properties. This is where the role of UV absorbers becomes critical.

Understanding the mechanism of UV absorbers is key to their effective application. These compounds function by absorbing harmful UV radiation within a specific wavelength range (typically 290-350 nm) and converting this energy into harmless heat. This process prevents the UV light from initiating free radical chain reactions within the polymer matrix, which would otherwise lead to material breakdown.

Among the various classes of UV absorbers, substituted benzoates, such as JADEWIN UV 120 (chemical name: 2,4-Di-tert-butylphenyl 3,5-di-tert-butyl-4-hydroxybenzoate), have gained significant traction. A key advantage of these compounds is their superior initial color compared to alternatives like benzotriazoles. This means they are less likely to impart unwanted yellowing or discoloration to the final product, making them ideal for applications where visual clarity is important.

Furthermore, the synergistic effect of UV absorbers with Hindered Amine Light Stabilizers (HALS) is a well-established strategy for achieving robust polymer protection. While UV absorbers act as primary screens, HALS function as radical scavengers, neutralizing any free radicals that might still form. When used in combination, these additives create a multi-layered defense against UV-induced degradation. For instance, JADEWIN UV 120 is recommended for use at levels of 0.2% to 1% in various polymers including Polypropylene, Polyethylene, TPO, PVC, EVA, unsaturated Polyester, ABS, and AS. This broad applicability underscores its utility in the industry.

For manufacturers seeking to enhance the durability and performance of their polymer products, selecting the right UV absorber is a crucial decision.
