UV-stabilizers, also known as UV stabilizers or UV absorbers, are organic compounds used to protect materials from the damaging effects of ultraviolet (UV) radiation. They are commonly added to polymers, plastics, and other materials to extend their lifespan and maintain their properties under prolonged exposure to sunlight. UV stabilizers work by absorbing or scattering UV light, preventing it from reaching the material and causing degradation. There are two main types of UV stabilizers: UV absorbers and UV quenchers. UV absorbers intercept UV radiation and convert it into heat, while UV quenchers deactivate excited states of the polymer molecules, preventing them from initiating degradation reactions. Common UV stabilizers include benzotriazoles, benzophenones, and hindered amines. These compounds are widely used in various industries, including automotive, construction, and packaging, to enhance the durability and performance of products exposed to outdoor conditions. The selection of UV stabilizers depends on the specific material, the intensity of UV exposure, and the desired level of protection.
