AB  - The purpose of the present research is to obtain waste of polymeric composite as 
      an insulator capacitive application. Rubber materials, once they end their useful 
      life, may be difficult to reuse or recycle. At present, research only uses one 
      tire recycling method, which involves grinding and separating steel and fibers 
      from vulcanized rubber, and then using the rubber particles for industrial 
      capacitors. The methodology for this research is to compare the permittivity (epsilon' 
      and epsilon'') between high-density polyethylene (HDPE) and the polymer matrix compound, 
      consisting of an HDPE polymeric matrix blended with end-of-life tire particles 
      (ground tire rubber (GTR)), to analyze the feasibility of using such tires as 
      electrically insulating materials (dielectrics). The incorporation of carbon 
      black in the GTR compounds modifies conductivity; GTRs carry a significant amount 
      of carbon black, and therefore some electrical properties may change 
      significantly compared to highly insulating polymer substrates. The performed 
      experimental study is based on a dynamic electric analysis (DEA) test developed 
      in the frequency range of 10(-2) Hz to 3 MHz and at different temperatures (from 
      35 to 70  degrees C) of different samples type: HDPE neat and HDPE compounds with 10%, 
      20% and 40% of GTR loads. A sample's electrical behavior is checked for its 
      dependence on frequency and temperature, focused on the permittivity property; 
      this is a key property for capacitive insulators and is key for examining the 
      possible applications in this field, for HDPE + GTR blends. Results for the 
      permittivity behavior and the loss factor show different electrical behavior. For 
      a neat HDPE sample, no dependence with frequency nor temperature is shown. 
      However, with the addition of 10%, 20%, and 40% amount of GTR the HDPE compounds 
      show different behaviors: for low frequencies, interfacial polarization 
      relaxation is seen, due to the Maxwell-Wagner-Sillars (MWS) effect, performed in 
      heterogeneous materials. In order to analyze thermal and morphological properties 
      the differential scanning calorimetry (DSC) test and scanning electron microscopy 
      (SEM) have been used. Results obtained show that adding waste tire particles in 
      an HDPE matrix allows HDPE + 40% GTR blends to act as a dielectric in capacitors, 
      increasing the capacitor dielectric efficiency in the low frequencies due to the 
      MWS effect, which increases the dielectric constant.
