Light Stabilizers / UV Absorbers

Light stabilizers / UV absorbers combat the degradation that plastics can undergo under the effects of sunlight, UV rays, heat and reaction with oxygen. The changes witnessed in a plastic can range from discoloration to formation of cracks. Addition of light stabilizers / UV absorbers can extend the life and improve the appearance of the plastic. Selection of a light stabilizer / UV absorber largely depends upon the substrate to be protected, its envisioned functional life and its sensitivity to photodegradation. The most commonly used light stabilizers in plastics are hindered amine light stabilizers (HALS); the most common UV absorbers are benzotriazoles, benzophenones and organic nickel compounds.

Selection Guide

Selection of Light Stabilizers for Polymers

Degradation is an undesirable process in most polymeric applications. It generally leads to changes in the chemical and physical structure of the polymer resulting in the loss of many useful properties. UV degradation of polymers can negatively affect molecular weight, impact resistance, elongation at break, gloss and color. By incorporating weathering stabilizers, the occurrence of such damages can slow down considerably. Explore, in detail, about basics of light stabilizers/UV absorbers and degradation mechanism in different polymers. Also, get tips to select the best suitable light stabilizers/UV absorbers & formulation examples for your polymer applications.
