Abstract: Conventional coating compositions have the disadvantage of being insufficiently coatable and having an unsatisfactory environmental stress cracking resistance. Now a coating composition has been found which has both good coating processability and environmental stress cracking resistance. It comprises a multimodal ethylene polymer, which contains from 80 to 100% by weight of ethylene repeating units and from 0 to 20% by weight of C3-C10 &agr;-olefin repeating units, has a density of between 0.915 g/cm3 and 0.955 g/cm3, and is a blend of at least a first ethylene polymer having a first average molecular weight and a first molecular weight distribution and a second ethylene polymer having a second average molecular weight, which is higher than said first average molecular weight, and a second molecular weight distribution, said blend having a third average molecular weight and a third molecular weight distribution.

Abstract: A cable-sheating composition and its use as outer sheath for a power cable or a communication cable are disclosed. The cable-sheating composition is a multimodal, preferably bimodal, mixture of olefin polymers, preferable ethylene plastics, having a density of about 0.915-0.955 g/cm3 and a melt flow rate of about 0.1-0.3 g/10 min, said olefin polymer mixture comprising at least a first and a second olefin polymer, of which the first has a density and a melt flow rate selected from (a) about 0.930-0.975 g/cm3 and about 50-2000 g/10 min and (b) about 0.88-0.93 g/cm3 and about 0.1-0.8 g/10 min.

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 polymer mixture, obtained by polymerization of at least one &agr;-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.
