What functions does ultraviolet absorbent have?

Ultraviolet absorbent can usually protect products like paints, plastics from degradation caused by the ultraviolet ray irradiation, and thus to extend the service life of these products. As we know, ultraviolet light can oxidize the plastics and other polymers and damage the appearance and mechanical functions of these products. Ultraviolet absorbent is an effective way is to prevent the harmful ultraviolet light.
