Abstract
The present invention relates to a cable jacket composition comprising a multimodal olefin copolymer, wherein said olefin copolymer has a density of 0.935-0.960 g/cm3 and MFR2 of 1.5-10.0 g/10 min and comprises a bimodal polymer mixture of a low molecular weight homo- or copolymer and a high molecular weight copolymer wherein the composition has ESCR of at least 2000 hours and wherein the numerical values of cable wear index and composition MFR2 (g/10 min) follow the correlation: Wear index<15.500+0.900*composition MFR2. The invention further relates to the process for preparing said composition and its use as outer jacket layer for a cable, preferably a communication cable, most preferably a fiber optic cable.
