New Breakthroughs in Hindered Amine Light Stabilizer Performance

摘要

The role of hindered amine light stabilizers (HALS) in the protection of polyolefins continues to expand. HALS ae resential components in formulations developed for outdoor use and have been proven to be effective thermo-oxidative stabilizers. The physicochemical properties of hindered amines have a profound effect on the hindered amine's performance as a stabilizer, and will also influence the reactivity of the HALS with other formulation components, environmental agents, etc. Some of these interactions can have a deleterious effect on end product aesthetics and service life.
