POLYMER COMPOSITION COMPRISING CARBON BLACK AND A CARRIER POLYMER FOR THE CARBON BLACK

摘要

A masterbatch (MB) comprising, preferably consisting of, (I) 20-50 wt% pigment based on the total amount of the masterbatch (100 wt%); (II) at least 40 wt% of at least one carrier polymer which is a multimodal high density polyethylene (HDPE) polymer having an MFR2 of 1 to 20 g/ min, a density of 940 to 965 kg/m 3 (pref 950 to 960) and a Mw/Mn of 5.5 to 20; and (IV) optionally further additives.
