EspañolProduct overview
A light stabilizer ( CAS 65447-77-0 ) serves as an additive for polymer products, providing protection against ultraviolet light energy, single-line oxygen burst, and hydrogen peroxide decomposition.
Applications
A light stabilizer is widely applicable in plastics, rubber, coatings, and synthetic fibers, it effectively shields against environmental factors. Light stabilizer 622, for instance, finds extensive use in PE applications like injection molding and film, as well as in EVA, PP fibers, polyurethanes, polyacetals, polyamide, elastomers, and adhesives. Often employed in combination with antioxidants and UV absorbers, it optimizes performance for outdoor use in various polymers.
