UV-P is a benzotriazole type UV absorber for plastics and other organic polymers. It protects the substrates into which it’s incorporated from degradation by UV light and retards yellowing and deterioration of mechanical properties. Its effect by selective absorption of the UV portion of sunlight and artificial light. This radiation, which is mainly responsible for the damage caused by UV light, is converted into harmless heat energy. It can be readily combined with antioxidants and other light stabilizers, and in many cases this gives a considerable improvement in the light and heat stability of the polymer.
