STRIPPABLE SEMICONDUCTIVE COMPOSITION COMPRISING LOW MELT TEMPERATURE POLYOLEFIN |
摘要 |
The present invention relates to a semiconductive polymer composition having easily controllable stripping characteristics, especially for an electric power cable. The semiconductive polymer composition comprises an ethylene copolymer comprising polar co-monomer units, wherein the amount of the polar co-monomer units in the ethylene copolymer is 10 wt.% or more, based on the total weight of the ethylene copolymer; an olefin copolymer comprising propylene monomer units and monomer units of an alpha-olefin having at least 4 carbon atoms, wherein the olefin copolymer has a melting point of 110 °C or less, and carbon black in an amount of from 10 to 50 wt.%, based on the total weight of the semiconductive polymer composition, wherein the olefin copolymer (B) is prepared by using a metallocene polymerisation catalyst. The composition provides improved strippability and enhanced mechanical as well as electrical property profile.
