Abstract
An insulating composition for communication cables (2) is disclosed as well as a telesingle wire (2) which comprises the insulating composition and a telecommunication cable (1) which comprises a plurality of telesingle wires (2) including the insulating composition.
The insulating composition comprises a multimodal olefin poll(mer mixture, obtained by polymerisation of at least one .alpha.-olefin in more than one stage having a density of about 0.920-0.965 g/cm3, a melt flow rate (MFR2) of about 0.2-5 g/10 min, an FRR21/2 >= 60, and an environmental stress cracking resistance (ESCR) according to ASTM D 1693 A/10 % Igepal, of at least 500 hrs, said olefin polymer mixture comprising at least a first and a second olefin polymer, of which the first is selected from (a) a low molecular weight (MW) olefin polymer with a density of about 0.925-0.975 g/cm3 and a melt flow rate (MFR2) of about 300-20 000 g/10 min, and (b) a high molecular weight (MW) olefin polymer with a density of about 0.880-0.950 g/cm3 and a melt flow rate (MFR21) of about 0.5-20 g/10 min.
The insulating composition comprises a multimodal olefin poll(mer mixture, obtained by polymerisation of at least one .alpha.-olefin in more than one stage having a density of about 0.920-0.965 g/cm3, a melt flow rate (MFR2) of about 0.2-5 g/10 min, an FRR21/2 >= 60, and an environmental stress cracking resistance (ESCR) according to ASTM D 1693 A/10 % Igepal, of at least 500 hrs, said olefin polymer mixture comprising at least a first and a second olefin polymer, of which the first is selected from (a) a low molecular weight (MW) olefin polymer with a density of about 0.925-0.975 g/cm3 and a melt flow rate (MFR2) of about 300-20 000 g/10 min, and (b) a high molecular weight (MW) olefin polymer with a density of about 0.880-0.950 g/cm3 and a melt flow rate (MFR21) of about 0.5-20 g/10 min.
