Summary:The present invention relates to a crosslinkable polyolefin composition for wire and cable applications, and particularly for low voltage (LV) and medium voltage (MV) cables, to a cable comprising said compositions and to the use of said compositions for increasing the tensile strength and/or flexibility of a cable. The crosslinkable polyolefin composition of the invention comprises (a) 50 to 99 wt.%, based on the total polyolefin composition, of one or more alpha-olefin copolymer(s) containing monomer units with polar groups and monomer units with hydrolysable silane groups, wherein the monomer units with polar groups are present in an amount of from 1 to 25 mol.% based on the total polyolefin composition, and (b) 1 to 50 wt.%, based on the total polyolefin composition, of a copolymer of ethylene and a C3 to C8 alpha-olefin co-monomer having a density of from 850 to 970 kg/m3 and a MFR2.16 of from 0.1 to 50 g/10 min, determined according to ISO 1133 at a temperature of 190 °C and a load of 2.16 kg. A cable comprising such a crosslinkable polyolefin composition and its use for increasing the tensile strength and/or flexibility of a cable are disclosed as well.
