Ultraviolet Absorber

Name:
Ultraviolet Absorber
Detailed information:
A substance that absorbs radiant energy in the wavelength of UV. The radiant energy absorbed is converted to heat (thermal energy). UV absorbers are added to unsaturated substances (plastics, rubbers, etc.) to decrease light sensitivity and consequent discoloring and degradation. Among compounds used are benzophenones, benzotriazoles, substituted acrylonitriles, and phenol-nickel complexes.See Absorption.
