摘要
Disclosed are a polypropylene-based flame-retardant insulating resin composition that has abrasion resistance and flexibility and is suitable for cables used in, in particular, vehicles, and an electric cable using the same. The composition comprises a polypropylene resin or reactor-made thermoplastic polypropylene resin that satisfies the predetermined ranges of abrasion resistance by a scrape test, bending elasticity by a three-point bending test and storage modulus by dynamic mechanical analysis. The composition also comprises an inorganic flame-retardant, and optionally further comprises a rubber and a modified resin containing a polar functional group.
