Basic characteristics and mechanism of action of UV-327 UV absorber

What is UV absorber UV-327?

UV absorber UV-327 is a highly efficient chemical compound and belongs to the benzotriazole UV absorber. Its chemical name is 2-(2′-hydroxy-5′-methylphenyl)benzotriazole, the molecular formula is C15H11NO2, and the molecular weight is 241.26 g/mol. UV-327 is known for its excellent UV absorption capacity and excellent thermal stability. It is widely used in plastics, coatings, fibers and other polymer materials to prevent degradation and aging caused by UV rays.

Mechanism of action of UV-327

1. Energy absorbing ultraviolet rays

The main function of UV-327 is to absorb ultraviolet energy and convert it into harmless heat energy to release it. This process can effectively prevent ultraviolet rays from directly acting on the material surface, thereby avoiding discoloration, cracking or degradation of the material due to photooxidation reaction. Specifically, UV-327 synergizes with adjacent hydroxyl groups through the benzotriazole ring in its molecular structure to form an efficient light-stabilizing system.

2. Prevent free radical generation

Ultraviolet radiation will cause the material’s molecular chain to break and free radicals, which will trigger a chain reaction and accelerate the aging process of the material. UV-327 can prevent the generation of free radicals by absorbing ultraviolet rays, thereby inhibiting the occurrence of this chain reaction. This is like cutting off fuel supply in time in a fire to prevent the fire from spreading.

3. Provide long-term protection

UV-327 has higher heat resistance and mobility resistance compared to other types of UV absorbers, which means it can remain stable under high temperature environments and is not easy to precipitate from the material. Therefore, it can provide electronic devices with longer-lasting protection and can effectively resist ultraviolet rays even under long-term use or harsh environmental conditions.

UV-327’s unique advantages

The reason why UV-327 is widely used in the protection of electronic equipment is inseparable from its unique physical and chemical properties. First of all, its absorption wavelength range is wide and can cover most UV areas (about 280-380 nm), ensuring a good shielding effect on UV rays of different wavelengths. Secondly, UV-327 has excellent compatibility and can be combined with a variety of polymer materials without affecting the original performance of the material. In addition, it also exhibits excellent light stability and does not significantly degrade or fail even under long periods of light.

To sum up, UV absorber UV-327 provides reliable ultraviolet protection for electronic devices through its unique molecular structure and mechanism of action. This “invisible armor” can not only significantly extend the service life of the equipment, but also maintain the integrity of its appearance and performance, protecting the durability of modern technological products.
