1-19. (canceled)
Polymer composition comprising
- (A) a polymer base resin comprising
- (A-1) a multimodal ethylene polymer having a density of 930 kg/m3 or less, and
- (A-2) a further ethylene polymer which is other than the multimodal ethylene polymer (A-1) and selected from
- (A-2-a) ethylene polymer produced in the presence of a coordination catalyst or
- (A-2-b) ethylene polymer produced in a high pressure polymerization process in the presence of a radical initiator, or mixtures thereof,
- wherein the amount of the multimodal ethylene polymer (A-1) is of 65 15 wt % to 96 wt % and the amount of the ethylene polymer (A-2) is of 4 wt % to 35 wt %, based on the total amount of the polymer base resin (A);
- and
- (B) carbon black;
- wherein the polymer composition has a MFR5 of 1.5 g/10 min to 10 g/10 min.
