UV radiation can have a significant impact on the performance and durability of various materials, such as plastics, coatings, and adhesives. Exposure to UV rays can cause discoloration, brittleness, and cracking, which can reduce the aesthetic and functional properties of the materials. To address this issue, many industries rely on UV absorbers, which are chemical compounds that can absorb and dissipate UV radiation before it can cause damage to the materials. One of the most effective and reliable UV absorbers in the market is UV-2908, which is produced by Ningbo Inno Pharmchem Co., Ltd., a leading supplier, factory, and manufacturer of specialty chemicals.
UV-2908, also known as Cytec Light Stabilizer Cyasorb UV 2908, Cytec Cyasorb UV 2908, Cytec UV 2908, Solvay Light Stabilizer CYASORB UV-2908, Solvay CYASORB UV-2908, Solvay UV-2908, or Light Stabilizer UV-2908, is a highly efficient UV absorber that can provide excellent protection against UV radiation. The active ingredient of UV-2908 is 3,5-di-tert-butyl-4-hydroxybenzoic acid n-hexadecyl, also known as cetyl 3,5-di-tert-butyl-4-hydroxybenzoate or hexadecyl 3,5-di-tert-butyl-4-hydroxybenzoate. This compound has a high molar extinction coefficient, which means that it can absorb a large amount of UV radiation in a broad wavelength range, from 290 to 400 nm.
UV-2908 is particularly suitable for applications that require long-lasting and high-performance UV protection, such as outdoor and automotive coatings, plastic films, and fibers. It can also be used in adhesives, sealants, and elastomers that are exposed to UV radiation during storage or use. UV-2908 can provide excellent light stability and resistance to yellowing, which can help maintain the appearance and quality of the materials over time. Additionally, UV-2908 is compatible with various polymers, such as polyolefins, polyesters, polycarbonates, and polyurethanes, which makes it versatile and easy to use in different formulations.
One of the main advantages of UV-2908 is its high thermal stability, which means that it can withstand high processing temperatures without degradation or loss of efficacy. This is particularly important in applications that require high-temperature processing, such as extrusion, injection molding, or blow molding. UV-2908 can also provide synergistic effects with other stabilizers, such as hindered amine light stabilizers (HALS), which can further enhance the UV protection and overall performance of the materials.
Another advantage of UV-2908 is its low volatility, which means that it has a low tendency to evaporate or migrate from the materials. This can reduce the risk of contamination, staining, or discoloration of adjacent surfaces, which is especially important in applications that require high optical clarity or color stability. UV-2908 can also provide good compatibility with other additives, such as antioxidants, antistatic agents, or slip agents, which can help optimize the formulation and processing of the materials.
UV-2908 is a high-quality and reliable UV absorber that can provide excellent protection and performance to various materials. It is produced by Ningbo Inno Pharmchem Co., Ltd., a leading supplier, factory, and manufacturer of specialty chemicals that has a proven track record of delivering innovative and cost-effective solutions to its customers. With its superior properties and compatibility, UV-2908 can help improve the durability, functionality, and aesthetics of various products, and enhance the value and competitiveness of the industries that rely on them.
