Comparative study of the presence of latex and polychloroprene in the behavior of sintered powder EPDMCR, ethylene-propylene- diene-monomer crumb rubber

Abstract

In this work, the mechanical behavior of sintered waste material of Ethylene-PropyleneDiene-Monomer Crumb Rubber (EPDMCR) is analyzed, optimizing the temperature and compression pressure. The results obtained showed that an increase in temperature and compression pressure gives a significant improvement in the mechanical properties of the material. We later mixed the EPDMCR particles with different percentages of adhesives with the aim of further improving the mechanical performance obtained from the sintered particles. The adhesives used in this study were latex and polychloroprene, and the optimum mechanical performance obtained came from mixes with polychloroprene, using a mix with 50% adhesive. The study was concluded with an analysis of images of the material using a scanning electron microscope (SEM), in order to observe the EPDMCR-Adhesive interaction.
