Impact of TMTD and CBS Accelerators on the Cure Rate Index in EPDMVulcanization Process and Mechanical Properties

Elastomer vulcanization is a chemical process that enhances the properties of elastomer products.Sulfur vulcanization is the most common method for cross-linking elastomers and improving theirmechanical properties and elasticity. In this study, EPDM was sulfur-cured using two differentaccelerators: TMTD and CBS. The results showed that TMTD exhibited better CRI compared toCBS. The CRI values for TMTD and CBS accelerators were ۸.۷ and ۲.۸, respectively. Thevulcanization of EPDM with TMTD facilitates the cross-linking of polymer chains by sulfur andaccelerators, improving the mechanical properties of the elastomer.
