2-(2H-Hydroxy-3-5-Di-tert-Amyllphenyl)benzotriazole: An Effective UV Absorber for Polymer Stabilization

Polymer materials are highly susceptible to degradation caused by exposure to UV radiation, which can lead to discoloration, embrittlement, and reduced mechanical properties. To prevent such degradation, UV stabilizers are widely used in various polymer applications, including plastics, coatings, adhesives, and fibers. One of the most effective UV stabilizers is 2-(2H-hydroxy-3-5-di-tert-amylphenyl)benzotriazole, also known as UV-328 or Tinuvin 328.

UV-328 is a highly efficient UV absorber that can effectively absorb both UV-A and UV-B radiation, with a maximum absorption peak at around 300 nm. This makes it an ideal choice for stabilizing polymers that are exposed to outdoor or high-intensity UV radiation, such as polyolefins, PVC, polyesters, and polycarbonates. UV-328 can also act as a synergist with other UV stabilizers, such as hindered amine light stabilizers (HALS), to provide enhanced protection against UV radiation.

One of the key advantages of UV-328 over other UV stabilizers is its high thermal stability, which enables it to maintain its effectiveness even at high processing temperatures. This is particularly important for polymer applications that require high-temperature processing, such as injection molding, extrusion, and blow molding. UV-328 is also highly compatible with various polymer matrices, and can be easily incorporated into polymer formulations without affecting their physical or chemical properties.

In addition to its excellent UV stabilization properties, UV-328 also offers several other benefits for polymer applications. It can act as an antioxidant, preventing the oxidation and degradation of polymers caused by heat, oxygen, and other environmental factors. It can also improve the weatherability and durability of polymer products, ensuring long-term performance and appearance.
