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 strain at break for the sulfur cross-linking system than the peroxide one. For the swelling test, the empirical equation used by Kumnuantip and Sombatsompop shows the best fitting for the degree of swelling – time data.}, keywords = {EBDM Foam,Mechanical Properties,peroxide and sulfur vulcanizates,tensile resistance,Abrasion and swelling test}, url = {https://icmep.journals.ekb.eg/article_29586.html}, eprint = {https://icmep.journals.ekb.eg/article_29586_b4e9030abbc370cd630188c57e2efef5.pdf} }
