Dielectric characteristics of various polymers (PVC, HDPE, EVA, PP, PS, PA and ABS) reinforced with out of use tires (GTR)
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 De...

| Sumario: | 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 µm, 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 30ºC to 120ºC, and with frequencies of 1·10-2 Hz, up to 3·106Hz. Finally, the fracture surfaces of the samples have been evaluated by scanning electron microscopy (SEM). |
