Cytec Industries recently developed a new light stabilizer, Cyasorb UV-2908. The company's researchers found that a stable system consisting of a combination of hindered hydroxybenzoate (HB) and antioxidants and high molecular mass hindered aniline light stabilizers (HALS) enables polyolefins to have excellent long-term thermal stability. . The Cyasorb UV-2908 light stabilizer made according to this finding is quite satisfactory and has no negative effect on thermal stabilizers such as dithioester compounds. The use of polyolefins together can simultaneously achieve both thermal and light stability. The role of the request. The trial showed that the combination of HB and dithioester (STDP) and HALS can significantly improve the long-term thermal stability of injection-molded polypropylene at medium and high temperatures. It can also increase the long-term UV stability of polypropylene and reduce the amount of stabilizer. (Tang Weijia)
