摘要 |
<p>A cable, in particular for power transmission, for telecommunications or for data transmission, or also combined power/telecommunications cables, wherein at least one coating layer consists of a recyclable material which is halogen-free and has superior mechanical and electrical properties. This material consists of a polymer mixture comprising: (a) a crystalline propylene homopolymer or copolymer; and (b) an elastomeric copolymer of ethylene with at least one alpha-olefin having from 3 to 12 carbon atoms, and optionally with a diene; the said copolymer (b) being characterized by a 200% tension set value (measured at 20 DEG C for 1 minute according to ASTM standard D 412) lower than 30%. <IMAGE></p> |
