Abstract
Various types of accelerators, thiuram (TMTD), thiazole (MBTS), and sulfenamide (CBS) are added into a silica filled natural rubber (NR) compound. Their effects on vulcanization properties are also investigated. TMTD shows a fast vulcanization rate and a higer maximum torque ($T_{max}$), as well as excellent mechanical properties (hardness, 300% modulus, tensile strength, elongation). MBTS shows a moderate vulcanization rate, a lower $T_{max}$, and mechanical properties. Finally, CBS shows a slow vulcanization rate but excellent mechanical properties. The same vulcanization trend can be found in carbon black filled NR compounds.
