Comparación de las características mecánicas y dieléctricas de varios polímeros mezclados con caucho de neumáticos fuera de uso (GTR) para su aplicación como aislante de calzado de trabajo industrial

Abstract

The massive manufacture of tires and their difficulty for subsequent  recycling, represents today, a serious environmental problem. There are  several methods to try to recycle used tires, one of them is mechanical  separation, in which the vulcanized rubber is separated from steel and  fibers, which results in a rubber that can be milled into small particles  (Ground Tire Rubber, or GTR). This rubber can be used in various  applications, such as the one presented by this research, in which, once  mixed with customary polymers, it should be used for the manufacture  of insulation for industrial work shoes. Therefore, the objective of this  study is to evaluate the results of mixing these GTR particles with  several commonly used polymer matrices (polymer + GTR), verifying  that both their mechanical and dielectric properties comply with the  standards established for the manufacture of the insulation for shoes  for industrial use. The analysis will be carried out using seven polymer  matrices mixed with different concentrations of GTR.
