UV Absorber UV-2908: An Effective Solution for Protecting Polymer Materials from UV Degradation

In today's world, polymer materials are widely used in various applications, from packaging materials to automotive parts. However, prolonged exposure to ultraviolet (UV) radiation from sunlight can cause these materials to degrade, leading to discoloration, cracking, and loss of mechanical properties. This is where UV absorbers like UV-2908 come into play. In this article, we will discuss the properties and applications of UV-2908, a product manufactured and supplied by INNO SPECIALTY CHEMICALS from China.

UV-2908 is a light stabilizer that belongs to the benzotriazole class of UV absorbers. Its chemical name is 3,5-di-tert-butyl-4-hydroxybenzoic acid n-hexadecyl ester, and it is also known by various synonyms and trade names, including Cytec Light Stabilizer Cyasorb UV 2908, Solvay Light Stabilizer CYASORB UV-2908, and Ultraviolet Absorber UV-2908. UV-2908 is a white or off-white powder with a molecular weight of 530.83 g/mol and a melting point of 55-58°C.

UV-2908 is highly effective in protecting polymer materials from UV degradation. It absorbs UV radiation in the range of 290-400 nm, which corresponds to the most damaging part of the solar spectrum. UV-2908 works by converting the absorbed UV energy into less harmful forms, such as heat, or by dissipating it through a series of chemical reactions. This prevents the UV radiation from reaching the polymer matrix, thereby reducing the rate of degradation.

UV-2908 is compatible with a wide range of polymer materials, including polyolefins, polyesters, polycarbonates, and polyamides. It can be used in various applications, such as films, fibers, coatings, and molded parts. UV-2908 is particularly useful in outdoor applications, where polymer materials are exposed to sunlight for extended periods. Examples of such applications include agricultural films, automotive parts, construction materials, and outdoor furniture.

UV-2908 is easy to incorporate into polymer formulations. It can be added during the polymerization process, or as a masterbatch in the form of pellets or powders. The recommended dosage of UV-2908 depends on the specific application and the degree of UV exposure. Generally, a dosage of 0.1-0.5% by weight of the polymer is sufficient to provide effective UV protection.

UV-2908 has several advantages over other UV absorbers. Firstly, it has a broad absorption range, which allows it to protect polymer materials from a wide range of UV radiation. Secondly, it has a low volatility, which means that it does not evaporate or migrate from the polymer matrix over time. This ensures long-lasting UV protection. Finally, UV-2908 is non-toxic and non-hazardous, which makes it safe for use in various applications.

In conclusion, UV-2908 is an effective solution for protecting polymer materials from UV degradation. It is a highly compatible and versatile UV absorber that can be used in a wide range of applications. Its broad absorption range, low volatility, and non-toxic nature make it an ideal choice for outdoor applications that require long-lasting UV protection.
