Beschreibung
Zusammenfassung:	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. La présente invention concerne un mélange-maître (MB) comprenant, de préférence constitué de, (I) 20 à 50 % en poids de pigment par rapport à la quantité totale du mélange-maître (100 % en poids) ; (II) au moins 40 % en poids d'au moins un polymère transporteur qui est un polymère multimodal de polyéthylène haute densité (PEHD) ayant un MFR2 de 1 à 20 g/min, une masse volumique de 940 à 965 kg/m3 (de préférence de 950 à 960) et un Mw/Mn de 5,5 à 20 ; et (IV) éventuellement d'autres additifs.
