Product Description
VIOCHEM  UV-9
                 Benzophenone UV Absorber                                       Characterization   UV-9 is an ultraviolet light absorber (UVA) of the benzophenone class, imparting good light stability when used in combination with a HALS or UV range. It shows good compatibility with polyolefins and plasticized PVC.                                                                               
Chemical Name    2-Hydroxy-4-methoxybenzophenone
CAS Number      131-57-7
Structure          UV-9

                                                                                 Applications       The main application of UV-9 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 for agricultural films. It can be used as well as a UV barrier to protect combination with HALS. UV-9 can be used in high density polyethylene molded articles e.g. in crates.UV-9 also protects a number of other polymers against degradation caused by light exposure such us plasticized PVC and rubbers.
