Abstract:
In the present Part II, the kinetic numerical model discussed in detail in Part I, is applied to the huge amount of experimental data collected by the authors. Rheometer curves are fitted numerically for three different curing temperatures, for all the curing agents investigated at a concentration equal to 150%, which have proved to be the most adequate to obtain optimal crosslinking of the EPDM under consideration. The comparisons with experimental data at three different temperatures allow estimating partial kinetic constants of the model as a function of the absolute temperature, with a direct comparison with simplified formulas provided by the peroxide producers. The application of the numerical kinetic model to a large variety of real scale examples allows a direct validation of the capabilities of the approach proposed, as well as an evaluation of the most suitable production parameters to use in practice (curing time and temperature, concentration and typology of the curing ag
ents) in order to maximize rubber output mechanical properties and crosslink homogeneity, without the need to perform costly experimental campaign.
