Generally, Crosslinked polyethylene(XLPE) is used as an insulating materials for power cables. However, there is a thermosetting polymer that cannot be recycled. For this reason, the demand for eco-friendly insulating materials of non-crosslinking type is increasing and many researches have been conducted on recyclable thermoplastic Polypropylene(PP). However, It is a difficult to apply because of high stiffness. To satisfy the material available for power cable, It can be mixed thermoplastic elastomers(TPE). Meanwhile, PP and TPE can remain metal impurities due to catalysts during manufacture, or metal impurities can be caused by external factors in the compounding process. These metal impurities can be a factor in reducing insulation. This study informs the impurity capturing agents can selectively and chemically remove metallic impurities. We found a PP-based composition used as an impurity capturing agents with excellent insulation performance.
