Antioxidant FR

Technical Datasheet | Supplied by Songwon
2,2,4-trimethyl-1,2-dihydroquinoline polymer. Used as a primary antioxidant in dry rubber application to maintain physical as well as surface properties with good color, very good anti-scorch, and good heat resistance - at low concentrations. High Purity TMQ manufactured by controlling the reaction and process to concentrate functional composition within a narrow molecular weight distribution. Also has high dimer content and reduced impurities including bis-products results in higher compatibility with rubbers, reduced bloom, as well as reduced fuming during processing. Low primary amine content minimizes undesirable dissolution of sulfur in rubber matrix. Provides good synergistic effects with 3C or 6C.
