Polymer composites of virgin high density poly ethylene (HDPE) and virgin polypropylene (PP) are prepared. PP of weight% of 20, 30 and 50 are reinforced to HDPE in the form of pellets. They are converted into raw polymer sheets using a two roll milling machine. The prepared raw sheets have undergone compression moulding to fabricate polymer sheets to study electrical properties like dielectric strength, surface resistivity and volume resistivity at atmospheric temperature and pressure. Result shows dielectric strength and volume resistivity decreases with addition of PP to HDPE, whereas surface resistivity increases. Crystal growth rate is observed using a cross polarised microscope (PLM). The microscopy results reveal, the PP crystallizes faster than HDPE and the growth rate declines for the polyblend; showing non-uniform and hazy spherulitic structure.
