“…Similar approaches following the same scheme may be also found in Milani and Milani and Milani et al . Essentially, the phenomenological model proposed by Leroy et al . assumes that during the induction and vulcanization steps, the overall formation of sulfur crosslinks can be described by a classic Kamal and Sourour formulation, which supposes a catalytic and autocatalytic second order apparent reaction mechanism.…”

A comprehensive experimental and numerical analysis aimed at investigating the rheometer behavior of Natural Rubber (NR) vulcanized with sulfur and two accelerators [N,N‐diphenylguanidine (DPG) and N‐terbutyl, 2‐benzothiazylsulfenamide (TBBS)] is presented. To fit experimental data, the general reaction scheme proposed by Han and co‐workers for vulcanized sulfur NR is re‐adapted and suitably modified, taking into account DPG and TBBS single contributions. An ad hoc interactive software based on GUI technology is utilized to fit experimental data, allowing estimating kinetic constants also by unexperienced users. Chain reactions initiated by the formation of macrocompounds responsible for the formation of the instable crosslinked polymer are accounted for. In the presence of two accelerators, reactions are assumed to proceed in parallel, making the hypothesis of negligible interactions, being their concentrations rather similar. From the kinetic scheme adopted, a closed form solution is found for the crosslinking density, with the only limitation that the induction period is excluded from computations. © 2016 Wiley Periodicals, Inc.

The vulcanization kinetics of Ethylene-propylene diene monomer (EPDM) rubber thermal insulation was studied by using rheometer under isothermal condition at different temperatures. The rheometry analysis was used to determine the cure kinetic parameters and predicting the optimum curing time of EPDM thermal insulation. The experimental results revealed that the curing curves of EPDM thermal insulation were marching and the optimum curing time decreased with the increasing of temperature. The kinetic parameters were determined from the autocatalytic model that showed a close fitting with the experimental results. It also indicated a suitability of autocatalytic model in characterizing the cure kinetics. The optimum curing time was predicted from autocatalytic model and the kinetic parameters were obtained by using the relationship between degree of conversion, cure temperature, and cure time. The predictions of cure time provided information on the actual curing characteristic of EPDM thermal insulation. The mechanical properties of EPDM thermal insulation with different vulcanization temperatures showed the same hardness, tensile strength and modulus at 300%, except at temperature 70 o C, while the elongation at breaking point decreased with the increasing temperature of vulcanization.
