Dragonsorb® 81 is a benzophenone-type UV absorber that is widely used in polyolefin and other polymers such as plasticized PVC and rubber products. It is mainly used in LDPE and LLDPE agricultural films, EVA copolymers, and HDPE injection products, such as turnover boxes, 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 have a synergistic effect with antioxidants and light stabilizers.
