Abstract
The present invention relates to a coaxial cable comprising a dielectric layer which comprises as a component (A) a propylene homo- or copolymer having strain hardening behaviour and to the use of propylene homo- or copolymer having strain hardening behaviour for the production of a dielectric layer of a coaxial or triaxial cable.
Claims11
A coaxial or triaxial cable comprising a dielectric layer which comprises as a component (A) a propylene homo- or copolymer having strain hardening behaviour.
Cable according to any of the preceding claims, wherein the ratio of components (A):(B) is from 1:99 to 60:40, more preferably from 25:75 to 60:40.
Cable according to any of the preceding claims wherein the propylene homo- or copolymer having strain hardening behaviour has a melt flow rate of 0.1 to 25 g/10 min at 230° C./2.16 kg.
Cable according to any of the preceding claims wherein the dielectric layer has been expanded, preferably by physical foaming.
Cable according to any of the preceding claims wherein the dielectric layer further comprises a nucleating agent, preferably in an amount of 0.01 to 0.05 wt %.
Use of propylene homo- or copolymer having strain hardening behaviour for the production of a dielectric layer of a coaxial or triaxial cable.
