Title
(EN) POLYOLEFIN COMPOSITION COMPRISING POLYPROPYLENE POLYMERS AND RECYCLED PLASTIC MATERIALS
(FR) COMPOSITION DE POLYOLÉFINE COMPRENANT DES POLYMÈRES DE POLYPROPYLÈNE ET DES MATIÈRES PLASTIQUES RECYCLÉES
Abstract
(EN) The present invention relates to a polyolefin composition comprising a) at least one heterophasic polypropylene copolymer with a melt flow rate MFR2 (230°C, 2.16 kg, measured according to ISO 1133) of at least 40 g/10 min, preferably of at least 60 g/10 min; b) at least one polypropylene homopolymer with a melt flow rate MFR2 (230°C, 2.16 kg, measured according to ISO 1133) of at least 400 g/10 min; and c) a blend (A) of recycled plastic material comprising polypropylene and polyethylene in a ratio between 3 : 7 and 12:1, which is recovered from a waste plastic material derived from post-consumer and/or post-industrial waste with a melt flow rate MFR2 (230°C, 2.16 kg, measured according to ISO 1133) of at least 5 g/10 min, wherein the polyolefin composition is characterized by a melt flow rate MFR2 (230°C, 2.16 kg, measured according to ISO 1133) of at least 20 g/10min.
(FR) La présente invention concerne une composition de polyoléfine comprenant a) au moins un copolymère de polypropylène hétérophasique ayant un indice de fluidité MFR2 (230 °C, 2,16 kg, mesuré conformément à la norme ISO 1133) d'au moins 40 g/10 min, de préférence d'au moins 60 g/10 min ; b) au moins un homopolymère de polypropylène ayant un indice de fluidité MFR2 (230 °C, 2,16 kg, mesuré conformément à la norme ISO 1133) d'au moins 400 g/10 min ; et c) un mélange (A) de matériau plastique recyclé comprenant du polypropylène et du polyéthylène en un rapport compris entre 3/ 7 et 12/1, qui est récupéré à partir d'une matière plastique usagée issue de déchets post-consommateur et/ou post-industriels avec un indice de fluidité MFR2 (230 °C) , 2,16 kg, mesuré conformément à la norme ISO1133) d'au moins 5 g/10 min, la composition de polyoléfine étant caractérisée par un indice de fluidité MFR2 (230 °C, 2,16 kg, mesuré conformément à la norme ISO1133) d'au moins 20 g/10 min.
