UV absorbers are crucial chemical compounds engineered to safeguard various materials from the detrimental effects of ultraviolet (UV) radiation. By absorbing...
A UV absorber is a chemical additive that protects materials by absorbing harmful ultraviolet (UV) radiation and converting it into less damaging energy, typically heat, thereby preventing material degradation.
UV absorbers work by absorbing UV light internally and dissipating the energy. UV blockers, like titanium dioxide, physically reflect or scatter UV light away from the surface.
They are widely used in plastics, paints, coatings, textiles, cosmetics, and packaging to prevent degradation, discoloration, and maintain product integrity when exposed to sunlight.
UV absorbers prevent photodegradation, which can manifest as discoloration (yellowing), embrittlement, cracking, chalking, and loss of strength in materials over time due to UV exposure.
