Polyolefin composition for use as an insulating material

The invention relates to a polymer composition, comprising (a) a polyolefin base resin which comprises at least (a1) a first olefin homo- or copolymer fraction, and (a2) a second olefin homo- or copolymer fraction, wherein the weight average molecular weight of the first fraction is lower than the w...

Beschreibung
Zusammenfassung:	The invention relates to a polymer composition, comprising (a) a polyolefin base resin which comprises at least (a1) a first olefin homo- or copolymer fraction, and (a2) a second olefin homo- or copolymer fraction, wherein the weight average molecular weight of the first fraction is lower than the weight average molecular weight of the second fraction, and (b) at least one additive selected from a polar copolymer; a low density polyethylene; an ether and/or ester group containing additive selected from the group consisting of polyethylene glycol, a glycerol ester compound, polypropylene glycol, an amido group containing fatty acid ester, ethoxylated and/or propoxylated pentaerythritol, an alpha-tocopherol ester, an ethoxylated and/or propoxylated fatty acid, and derivatives thereof; or mixtures of these additives.
