Abstract
A polymer composition is provided with improved stress whitening resistance, having at least one thermoplastic polymer material and a dielectric liquid. A process for preparing the polymer composition, a cable having at least one electrically insulating layer obtained from the polymer composition, and a process for preparing the cable are also provided.
Claims17
A polymer composition comprising at least one polypropylene-based thermoplastic polymer material and a dielectric liquid, wherein the dielectric liquid comprises at least one compound corresponding to formula (I) below:
- R1-A-R2 (I)
- in which R1 and R2, identical or different, are unsubstituted aryl groups and the element A represents a single bond or an alkylene group,
- wherein the polypropylene-based thermoplastic polymer material comprises at least one homopolymer or one copolymer of propylene P1, and at least one homopolymer or one copolymer of α-olefin P2.
