Products Usage
UV Absorber 531 has multiple applications.
Its main use is in combination with a HALS for the light stabilization of low density and linear low density polyethylene, as well as ethylene - vinyl acetate copolymers in agricultural films. It can also serve as a UV barrier to protect the contents of packages in both industrial and consumer applications. Additionally, when combined with HALS, it can be used in high density polyethylene molded articles, such as in crates.
Furthermore, UV Absorber 531 protects a number of other polymers against degradation caused by light exposure, like plasticized PVC and rubbers.
Moreover, it can be used in combination with antioxidants, phosphites and other light stabilizers.
