Evaluación de las propiedades físicas y mecánicas de una mezcla de caucho vulcanizado con polietileno de alta densidad reciclado en proporción 80:20

Abstract

Abstract: This research addresses the physical and mechanical properties of high-density polyethylene, or HDPE, and a blend composed of vulcanized rubber and HDPE in a ratio of 80% and 20%, respectively. The methodological analysis was performed in the industrial engineering laboratory, where each material underwent the necessary treatment for its subsequent composition through the thermopressing process. Mechanical tests such as tensile and compression were performed using a universal testing machine. Physical hardness tests were also performed using manual instruments. The density test was performed in the chemical engineering laboratory using instruments from the same laboratory. To obtain the results, graphs were created for better interpretation, where the tensile modulus, maximum stress, maximum strain, and yield strength were analyzed. Comparison graphs were developed between the HDPE and the blend. The results showed that HDPE had better physical and mechanical characteristics than the rubber mixture.
