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
Molecular weight 228.2
Appearance Light yellow crystalline power
Melting Point 62-64ºCLoss on drying 0.5%maxAsh 0.1%max
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.
