1.UV-531 is a high performance benzophenone UV absorber with strong absorption of UVA (especially below 340nm)and UVB, it appears light yellow;
2. lt shows good compatibmy with polyolefin and flexible PVC, low migration and"blooming";
3.Good thermal stability and low volatile reduce the loss while processing, UV-531 can be dissolved in toluene,chloroform, dichloromethane, ethyl acetate, and acetone. lt is insoluble in water.
4.UV-531 is mainly combined with a hindered amine light stabilizer for use in low density and inear low density polyethylenefor agricultural films, and EVA copolymers；
5.lt can also be used as a light stabilizer to protect the contents of industrial andconsumer packaging materials. In addition；
6.UV-531 can also be used in HDPE injection molded products such as totes.UV-531 also retards the degradation of other types of polymers such as plasticized PVC and rubber due to exposure tosunlight,UV-531 can be used in combination with antioxidant
