In the realm of polymer science and manufacturing, preserving the integrity and appearance of materials exposed to sunlight is a paramount concern. Ultraviolet (UV) radiation can initiate a cascade of degradation processes, leading to discoloration, loss of mechanical properties, and reduced product lifespan. To effectively combat these issues, specialized additives known as UV absorbers are employed. Among the most effective and widely used is the benzotriazole class, exemplified by our high-quality Benzotriazole UV Absorber, CAS 3846-71-7. NINGBO INNO PHARMCHEM CO.,LTD. is a leading manufacturer and supplier offering this crucial component to the global market.

The chemical structure of Benzotriazole UV Absorber, 2-(2H-benzotriazol-2-yl)-4,6-di-tert-butylphenol, grants it exceptional UV-absorbing capabilities. Its primary function is to absorb UV light in the range of 300-400 nm, a spectrum particularly damaging to many organic materials. Upon absorbing UV photons, the molecule undergoes reversible tautomerization, dissipating the energy as heat without causing irreversible chemical changes to itself or the surrounding polymer matrix. This mechanism provides excellent photostability and a long service life for the additive itself.

Key properties that make this UV absorber highly desirable for industrial applications include its strong UV absorption, low volatility, and good compatibility with various polymers. Its white to off-white crystalline powder appearance ensures ease of handling and incorporation into formulations. With a high assay of 99% purity, manufacturers can rely on consistent performance and predictable results. Its effectiveness in preventing discoloration and maintaining physical properties makes it an indispensable additive for plastics, such as PVC and unsaturated polyesters, as well as for protecting films and fibers.

The applications for Benzotriazole UV Absorber are diverse and critical. In the plastics industry, it is used to enhance the weatherability of products exposed to outdoor environments. This includes items like automotive components, construction materials, outdoor furniture, and agricultural films. For instance, incorporating this UV absorber into the formulation of PVC window profiles or exterior cladding significantly extends their resistance to sun-induced fading and degradation. Similarly, in the textile industry, it helps preserve the color and strength of synthetic fibers.
