The modern world relies heavily on plastics, but their susceptibility to degradation from UV radiation presents a significant challenge. Understanding the chemistry behind UV protection additives is key for product formulators and procurement managers. Hexadecyl 3,5-di-tert-butyl-4-hydroxybenzoate, commonly known as UV-2908, stands out as a sophisticated solution in this domain. As a leading UV absorber manufacturer in China, NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of supplying this essential compound.

At its core, UV-2908 is a benzoate-type UV absorber. Its molecular structure, specifically the presence of a hydroxyl group adjacent to a benzene ring and bulky tert-butyl groups, is crucial for its efficacy. This configuration allows the molecule to absorb UV radiation, particularly in the UV-A and UV-B ranges, which are most damaging to polymers. Upon absorbing a UV photon, the molecule undergoes a rapid intramolecular proton transfer, a reversible process that dissipates the absorbed energy as heat. This photophysical cycle allows the UV absorber molecule to repeatedly absorb UV light without being consumed, providing long-lasting protection to the polymer matrix.

The technical specifications of Hexadecyl 3,5-di-tert-butyl-4-hydroxybenzoate highlight its suitability for demanding applications. Its low volatility is a significant advantage; polymers processed at high temperatures are less likely to lose the stabilizer, ensuring sustained protection throughout the product's lifecycle. The compound also boasts minimal color contribution, which is vital for applications where aesthetic properties are paramount, such as in clear films or brightly colored products.

For businesses seeking to buy Hexadecyl 3,5-di-tert-butyl-4-hydroxybenzoate, NINGBO INNO PHARMCHEM CO.,LTD. offers a reliable source. We provide competitive pricing of UV-2908 for polyolefins, reflecting our commitment to delivering high-value solutions to our clients.
