In the realm of material science and chemical manufacturing, safeguarding products from the detrimental effects of ultraviolet (UV) radiation is a constant pursuit. Polymers, coatings, and other organic materials are susceptible to photodegradation, leading to a loss of performance, aesthetic appeal, and structural integrity. Benzotriazole UV absorbers, a class of highly effective compounds, are instrumental in preventing such damage. Among them, UV Absorber UV-328 stands out for its exceptional performance characteristics and broad applicability.

UV Absorber UV-328, identified by CAS Number 25973-55-1, is a chemical compound characterized by its efficient absorption of UV radiation, particularly in the 300-400 nm range, with a pronounced peak at 345 nm. This ability to absorb and dissipate UV energy as heat makes it an excellent protector against UV-induced degradation. Its chemical structure, 2-(2H-benzotriazol-2-yl)-4,6-di-tert-pentylphenol, confers excellent compatibility with a wide variety of polymer matrices, including polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), polyesters, and polycarbonates. This compatibility ensures seamless integration into formulations without negatively impacting the material's other properties.

As a leading manufacturer and supplier of specialty chemicals, we are committed to providing high-quality UV absorbers that meet the stringent demands of our clients. Our UV Absorber UV-328 is manufactured with a purity of 99% or higher, ensuring consistent performance and reliable protection. Key properties that make UV-328 highly desirable include its low volatility, which minimizes loss during high-temperature processing, and its excellent wash resistance, ensuring long-term effectiveness in the final product. These attributes are critical for applications requiring extended durability, such as outdoor furniture, automotive components, and protective coatings.

For professionals in the manufacturing and formulation industries looking to buy UV Absorber UV-328, understanding its role and procurement is vital. Typically, it is used at concentrations ranging from 0.1% to 1.0% by weight, depending on the specific polymer and the required level of UV protection. The ability to synergistically combine UV-328 with other stabilizers, such as hindered amine light stabilizers (HALS), further enhances its protective capabilities, offering a comprehensive defense against environmental degradation. We offer competitive pricing for bulk purchases, making it a cost-effective solution for achieving superior product performance.
