Polymer chemistry is a cornerstone of modern material science, driving innovation across countless industries. However, a persistent challenge in polymer application is their susceptibility to degradation caused by ultraviolet (UV) radiation. This degradation can severely compromise a polymer’s physical and aesthetic properties, leading to premature failure and increased costs. At NINGBO INNO PHARMCHEM CO.,LTD., we understand the critical role of protective additives. This article highlights the fundamental importance of UV absorbers in polymer chemistry and introduces our high-quality UV Absorber 897 as a solution for formulators seeking reliable UV protection.

Understanding UV Degradation Mechanisms in Polymers
When polymers are exposed to UV light, the energy from photons can excite electrons within the polymer chains. This excitation can lead to bond scission, chain scission, cross-linking, and the formation of free radicals. These processes collectively result in photodegradation, manifesting as embrittlement, discoloration, loss of tensile strength, chalking, and surface cracking. The severity of degradation depends on factors such as the polymer type, the intensity and wavelength of UV radiation, exposure duration, and the presence of other environmental factors like heat and oxygen.

How UV Absorbers Function in Polymer Matrices
UV absorbers are meticulously designed molecules that preferentially absorb UV radiation within a specific wavelength range (typically 290-400 nm). Upon absorbing UV photons, the UV absorber molecule undergoes a rapid, reversible internal conversion process, transforming the high-energy UV radiation into low-energy heat, which is then dissipated harmlessly. This process effectively intercepts the UV energy before it can initiate damaging reactions within the polymer. To ensure long-term effectiveness, formulators often seek UV absorbers that are photostable and do not readily migrate or leach out of the polymer matrix. The efficiency of a UV absorber is also influenced by its concentration and the thickness of the polymer part, making precise formulation crucial.
