  • detailed description
  • Product Name: UV-P ( (Tinuvin P)

    Chemical Name: 2-(2-Hydroxy-5-methyl-phenyl)-benzotriazole           

    CAS NO.: 2440-22-4






    White to slight yellow crystal powder

              Melting point 

                      138- 135 

              Loss on dry






    Uses: It is a benzotriazole type ultraviolet light absorber (UVA), imparting good light stability 

    for plastics and other organic polymers. UV-P protects polymers as well as organic pigments 

    from UV radiation helping to preserve the original appearance and physical integrity of engi-

    -neered plastics, elastomers, PVC, adhesives, and polyurethanes during outdoor weathering. 

    1. Unsaturated Polyester : 0.2-0.5wt% based on polymer weight

    2. PVC: Rigid PVC : 0.2-0.5wt% based on polymer weight ; Plasticized PVC : 0.1-0.3wt% based 

        on polymer weight

    3. Polyurethane : 0.2-1.0wt% based on polymer weight

    4. Polyamide : 0.2-0.5wt% based on polymer weight


    Packing: in 25kg net drum


    Storage: It may be stored up to two years in a sealed container. Containers should be stored in a 

    cool, dry area. Extended storage at elevated temperatures or exposure to direct heat or sunlight 

    could reduce product life. Keep containers sealed when no in use.
