Title (EN) POLYOLEFIN COMPOSITION WITH IMPROVED SURFACE APPEARANCE
(FR) COMPOSITION DE POLYOLÉFINE PRÉSENTANT UNE APPARENCE DE SURFACE AMÉLIORÉE
Abstract:
(EN) The present invention is directed to a heterophasic polypropylene composition (HECO1) and the use thereof to reduce the amount of flow marks of an injection moulded polyolefin composition. Further, the present invention is directed to a polyolefin composition (C) comprising a polyolefin (PO), said heterophasic polypropylene composition (HECO1) and optionally a filler as well as an article comprising said polyolefin composition (C).
(FR) La présente invention concerne une composition de polypropylène hétérophasique (HECO1) et son utilisation pour réduire la quantité de lignes de coulée d'une composition de polyoléfine moulée par injection. En outre, la présente invention concerne une composition de polyoléfine (C) comprenant une polyoléfine (PO), ladite composition de polypropylène hétérophasique (HECO1) et éventuellement une charge ainsi qu'un article comprenant ladite composition de polyoléfine (C).
