Dragonsorb®-81Product introduction
Dragonsorb®-81 is a benzophenone type UV absorber, widely used in polyolefin and other polymers such as plasticized PVC and rubber products. It is mainly used in LDPE and LLDPE of agricultural film, EVA copolymer and HDPE injection products, such as turnover box, to slow down the degradation of products caused by exposure to sunlight. At the same time, it can be used as a UV shielding agent to protect the contents of industrial products and consumer packaging materials. In addition, it can play a synergistic effect with antioxidant and light stabilizer.
