The role of thermo-oxidative aging at different temperatures on the crystal structure of crosslinked polyethylene

In order to investigate the role of thermo-oxidative aging on the crystal structure of crosslinked polyethylene (XLPE) at temperatures below and above the melting point, thermo-oxidative aging was conducted on XLPE cable insulation at 100, 120, 140 and 160 °C respectively. The crystal structure of the fresh sample and aged samples was characterized by X-ray diffraction, differential scanning calorimetry (DSC) and scanning electron microscopy...
