Improving the High-Temperature Mechanical Properties and DC Electrical Properties of Polypropylene Insulation Materials through Grafting and Cross-Linking Modification
Thermoplastic polypropylene (PP) has been widely regarded as a promising alternative to cross-linked polyethylene (XLPE) for cable insulation owing to its excellent recyclability. However, PP exhibits poor mechanical toughness at room temperature, and blending with low-modulus elastomers, although effective for tough...
