Uv Abosorber

Ultraviolet absorber is a kind of light stabilizer, which can absorb the ultraviolet part of sunlight and fluorescent light source without changing itself. Under sunlight and fluorescence, plastics and other high-molecular materials produce auto-oxidation reactions due to the action of ultraviolet rays, which leads to degradation and deterioration of polymers, resulting in deterioration of appearance and mechanical properties. After adding the ultraviolet absorber, this high-energy ultraviolet can be selectively absorbed to make it into harmless energy to be released or consumed.

Different types of polymers have different wavelengths of ultraviolet rays that degrade them. Different ultraviolet absorbers can absorb different wavelengths of ultraviolet rays. When used, the ultraviolet absorber should be selected according to the type of polymer.
