Abstract
The present invention relates to a cable comprising a conductor surrounded by one or more layers, wherein at least one layer comprises a polymer composition comprising a copolymer of ethylene with one or more comonomers, to a process for producing the cable and to a polymer composition suitable as a cable layer material.
Claims16
A cable comprising a conductor surrounded by one or more layers, wherein at least one layer comprises a polymer composition comprising a copolymer of ethylene with one or more comonomers, wherein the ethylene copolymer has a density of less than 945 kg/m3, an Mz/Mw of at least 2.45 and wherein the ethylene copolymer is obtainable by polymerising ethylene in the presence of a single site catalyst and an activator for said catalyst.
A polymer composition comprising a copolymer of ethylene with one or more comonomers, wherein the ethylene copolymer has a density of less than 945 kg/m3, an Mz/Mw of at least 2.45, is obtainable by polymerising ethylene in the presence of a single site catalyst and an activator for said catalyst, and has an MFR2 of 0.2 to 10 g/10 min.
