Application

It is a highly efficient asymmetric hindered phenolic antioxidant, which has a good antioxidant effect on styrene polymers, especially impact modified styrene, ABS, MBS, SB, SBR and POM homopolymers and copolymers. It is also very useful for the stability of polyurethane, polyamide, thermoplastic polyester and other polymers. AO-245 is also an effective chain terminator in PVC polymerization process. In addition, this product has no effect on the polymer reaction, used for high impact polystyrene, polyvinyl chloride, can be added to the monomer before polymerization.
