UV Absorbers

A group of chemical substances known as UV absorbers are primarily made to shield various materials and goods from the damaging effects of ultraviolet (UV) radiation. Numerous sectors, including those of plastics, coatings, textiles, and cosmetics & skincare, use these compounds extensively. UV absorbers are an essential line of defense against UV rays' deteriorating and discoloring effects, which can cause material degradation, shorten the lifespan of a product, and degrade the aesthetics. By absorbing the incoming UV light, these UV-absorbing substances stop it from entering and harming the underlying material.
