Patent ID: 8319102

Claim:
An insulation layer for cables consisting of a polypropylene composition consisting of a. a polypropylene base resin (A), which comprises a heterophasic propylene copolymer consisting of i. an isotactic propylene homo- and/or copolymer as matrix phase having a comonomer content of 0.5 to 10 wt %, based on the total amount of propylene matrix phase, and ii. a propylene copolymer as dispersed phase having a comonomer content of 20 to 80 wt %, based on the total amount of dispersed phase, in an amount of 50 to 90 wt % based on the total polypropylene composition; and b. a polar ethylene polymer (B), in amount of 10 to 50 wt %, based on the total polypropylene composition; wherein the polar ethylene polymer (B) comprises polar comonomers of C1- to C6-alkyl acrylates, C1- to C6-alkyl methacrylates, acrylic acids, methacrylic acids, or a mixture thereof.
