UVstabilatoren

UV stabilizers, also known as UV absorbers or UV filters, are organic compounds used in polymers and plastics to protect them from the damaging effects of ultraviolet (UV) light. UV light, particularly UV-B and UV-C, can cause degradation of polymers through processes such as chain scission, cross-linking, and oxidation, leading to discoloration, loss of mechanical properties, and reduced lifespan of the material.

UV stabilizers work by absorbing UV light and converting its energy into heat, thereby preventing it from reaching the polymer and causing degradation. They are typically added to polymers during the manufacturing process or applied as coatings to the surface of the material. Common types of UV stabilizers include benzotriazoles, benzophenones, and hindered amines, each with its own mechanism of action and specific applications.

The selection of a UV stabilizer depends on various factors, including the type of polymer, the intended use of the material, and the environmental conditions it will be exposed to. Effective UV stabilization is crucial for maintaining the performance and longevity of polymers in applications such as outdoor furniture, automotive parts, and packaging materials.
