Dragonsorb®-120 is a sterically hindered hydroxybenzoate UV absorber, which converts UV radiation into heat energy through reversible chemical rearrangement. Compared with benzotriazole UV absorbers, it can provide more excellent initial color; has synergistic effect with hindered amine light stabilizer; can be used with hindered phenol antioxidant, phosphite antioxidant and hindered amine light stabilizer at the same time to improve the weatherability of outdoor products; can be used with benzotriazole UV absorbers at the same time to improve the weatherability of products, such as TPO cars Bumper. The addition amount in PP, PE, TPO, PVC, EVA, unsaturated polyester, ABS, as is 0.20-1.0%
