Material and Apparatus Used for the Study

The rubber used was the EPDM compound described in Table 3.2 with 2% peroxide. The Monsanto 2000 E MDR is used under isothermal conditions, while the simulation is done by calculation. The thickness of the sample is taken as equal to 0.2 cm. A calorimeter C 80 was used in scanning mode with a heating rate of 0.2°C/min and a sample of around 6 g. 

The characteristics of cure and of heat transfer are shown in Table 3.7. 

In scanning mode of the MDR, the temperature of the dies and the rubber starts at room temperature (25°C) and increases constantly with time.
