Light Stabilizers / UV Absorbers

Based on 1911 products - Last update on the Jun 26, 2025

Light stabilizers, including UV absorbers, are additives used in plastics to prevent degradation caused by ultraviolet (UV) radiation, resulting in a clear and durable appearance. These agents function by absorbing or reflecting UV light, thereby protecting the polymer matrix from photo-oxidation and maintaining its mechanical properties. Key features include enhanced UV resistance, improved color retention, and extended product lifespan. Light stabilizers are particularly suitable for applications in outdoor furniture, automotive components, and agricultural films. 

Alternatives to light stabilizers include antioxidants. Current trend is the development of multifunctional stabilizers that combine UV protection with other stabilizing effects. Subtypes include Hindered Amine Light Stabilizers (HALS) and UV absorbers like benzotriazoles and benzophenones.
