Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Science - Department of Physics Summary: In this thesis, EPDM rubber loaded with different concentrations of azodicarbonamide (as a foaming agent) using two different vulcanizing systems was subjected to the mechanical, compression and swelling tests at room temperature (300{u00B0}K). Samples vulcanized by peroxide reveal more advantage over that vulcanized by sulfur, especially for the amount of specific gravity and the compression test. The tensile test shows a noticeable increase in the true stress and true strain at break for the sulfur vulcanizing system than those of the peroxide vulcanizing system. For the swelling test, the empirical equation used by Kumnuantip and Sombatsompop shows the best fitting for the degree of swelling time data
