Abstract
The invention relates to a pigmented cable jacket comprising a polymer composition which comprises a multimodal polyolefin, preferably polyethylene, and pigment composition comprising a color pigment wherein a blend of said pigment composition and said polymer composition is showing an average diameter of spherulites as determined according to the dissolution-recrystallization method which is at most 50% lower, more preferred at most 30% lower and still more preferred at most 10% lower than the average diameter of spherulites in the non-blended polymer composition as determined according to the dissolution-recrystallization method. Further, the invention relates to the use of a color pigment for the production of such a pigmented cable jacket comprising a polymer composition which comprises a multimodal polyolefin, preferably polyethylene, and a pigment composition comprising said color pigment wherein said pigment is a non-warping pigment and to the use of a multimodal polyolefin, preferably polyethylene, for the production of such a pigmented cable jacket comprising a polymer composition which comprises said multimodal polyolefin and a pigment composition comprising a color pigment wherein said pigment is a non-warping pigment.
