Influence of PP‐g‐MAH and POE‐g‐MAH on the High‐Temperature Dielectric Properties of PP/POE Composites for HVDC Cable Insulation

High Voltage, EarlyView.
ABSTRACT Polypropylene (PP) is recyclable and offers excellent insulation, but it requires elastomer blending for cable applications due to its brittleness. Although polyolefin elastomer (POE) enhances mechanical properties, it degrades dielectric performance, particularly at high temperatures.
