| Abstract | The aim is to determine the optimal expansion pressure of the rubber foam in the mold to determine the curing time that ensures good mechanical properties. In the experiment, the temperature was examined in three levels: 130, 140, and 150?C, for 20 min. Additionally, 8 compounds were examined with either DPT or ADC blowing agents. The experiment results indicated that the compressive stress and absorbed energy showed a similar trend, which was directly changed by both temperature and blowing agent. The appropriate compounds were compound 4 with 12 phr ADC and compound 5 with 3 phr DPT with the optimal pressure of 0.22 bar and 0.17 bar, respectively. Both ensured the high absorbed energy and high compression set. By determining the optimal internal pressure, the energy consumption of the NR foaming process can be calculated. In addition, the energy consumption was significantly changed by the area ratio. |
