UV Stabilizers

Light stabilizers (LS) such as radical scavenger and UV absorbers, combat the degradation that the plastic material undergoes under the combined effects of sunlight, artificial light and heat. The addition of LS to polymers extends their life cycle and improves their appearance. The selection of a LS largely depends upon the composition of the substrate to be protected, its envisioned functional life and its sensitivity to photodegradation. The most commonly used LS in polymers are hindered amine light stabilizers (HALS) generally combined with UV absorbers such as benzotriazoles and benzophenones.
