Resum:
The massive storage of reused tires constitutes a serious environmental problem. This article focuses on finding a new application for these reused tires (GTR), and for this, the dust from the reused tires has been mixed with different thermoplastic polymers such as Polyvinyl Chloride (PVC), High Density Polyethylene (HDPE), Ethylene Vinyl Acetate (EVA), Polypropylene (PP), Acrylonitrile Butadiene Styrene (ABS), Polystyrene (PS) and Polyamide (PA), checking until the concentration values in GTR allow these new compounds maintaining its dielectric properties within acceptable values, and therefore, its possible industrial applications in the manufacture of insulators for electrical cables. Specifically, the dust from reused tires and with a particle size less than 200 mu m, has been mixed with the polymers with four concentrations 5%, 10%, 20% and 50% in GTR, analyzing conductivity, permittivity, dielectric loss factor, dielectric relaxations, etc. in a temperature range of 30 degrees C to 120 degrees C, and with frequencies of 110-2 Hz, up to 3106Hz. Finally, the fracture surfaces of the samples have been evaluated by scanning electron microscopy (SEM).
