Antioxidant RD by Songwon is 2,2,4-trimethyl-1,2-dihydroquinoline polymer-based primary antioxidant in dry rubber application. It maintains physical and surface properties with good color, very good anti-scorch as well as good heat resistance. Antioxidant RD reduces the bloom due to high compatibility with rubbers. Low primary amine content minimizes undesirable dissolution of sulfur in rubber matrix. It offers good synergistic effects with 3C or 6C.
