摘要： 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 ethylene 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.
