PolyAdds Antioxidant Newanox 245 is highly effective in styrene polymers, especially impact-modified polystyrene (HIPS), ABS, MBS, SB, and SBR latexes, as well as in POM homopolymers and copolymers. In addition to imparting thermal stability to the final polymer, it also acts as a chain terminator in PVC polymerization.
