This material comprises a polymer mixture of a crystalline propylene homopolymer or copolymer and an elastomeric copolymer of ethylene with at least one alpha-olefin having from 3 to 12 carbon atoms, and optionally containing a diene. The copolymer is characterized by a 200% tension set value of lower than 30% (measured at 20° C. for 1 minute according to ASTM standard D 412). The cable also includes a flame-retardant polymer composition.
