Viochem UV-531

Methanone, 2-hydroxy-4-(octyloxy)-phenyl. Acts as a UV absorber. Used in combination with a HALS for the light stabilization of low density and linear low density polyethylene as well as ethylene-vinyl acetate copolymers for agricultural films. It can be used as well as a UV barrier to protect combination with HALS UV-531 can be used in high density polyethylene molded articles e.g. in crates. Also protects a number of other polymers against degradation caused by light exposure such us plasticized PVC and rubbers. Can be used in combination with antioxidants, phosphates and light stabilizers. Is particularly suitable for thick films.
