  Uses: This product is ultraviolet absorbent with high molecular weight, and has outstanding light 

  stability for polymers. This product is widely used in food and drugs to allow to be used with other 

  light stabilities or antioxidants. It is mainly used in polyester, polycarbonate, etc. It is a high molecular 

  weight ultraviolet light absorber (UVA) of the hydroxyl phenyl benzotriazole class, imparting outstanding 

  light stability to polymers usually processed at high temperatures such as polycarbonate, polyesters, 

  polyacetal, polyamides, polyphenylene sulfide, polyphenylene oxide, aromatic copolymers, thermoplastic 

  polyurethane and polyurethane fibers, where loss of UVA is not tolerated as well as for polyvinylchloride, 

  styrene homo-and copolymers. Applications include molded articles, films, sheets and fibers.UV 234 has 

  world wide Food Contact Approvals in most polymers and is especially suitable in packaging applications 

  for food, consumer care products and pharmaceuticals.

   

   

   

   

  Packing: in 25kg net drum

   

   

   

   

  Storage: Storing in dry,airproof and lucifugal conditions.
