Title (EN) COMPOSITION COMPRISING HETEROPHASIC PROPYLENE COPOLYMER
(FR) COMPOSITION COMPRENANT UN COPOLYMÈRE DE PROPYLÈNE HÉTÉROPHASIQUE
Abstract:
(EN) The invention relates to composition comprising (A) a propylene-based polymer, (B1) a first elastomer of ethylene and α-olefin comonomer having 4 to 10 carbon atoms, (B2) a second elastomer of ethylene and α-olefin comonomer having 4 to 10 carbon atoms and (C) an inorganic filler, wherein (B1) the first elastomer has a density of 0.850 to 0.890 g/cm3 and a melt flow index of 5 to 50 dg/min measured in accordance with ASTM D1238 using a 2.16 kg weight and at a temperature of 190 °C, wherein (B2) the second elastomer has a density of 0.850 to 0.890 g/cm3 and a melt flow index of 0.55 to 4 dg/min measured in accordance with ASTM D1238 using a 2.16 kg weight and at a temperature of 190 °C, wherein the total amount of (B1) the first elastomer and (B2) the second elastomer is 2 to 30 wt% based on the total composition, wherein the amount of (C) the inorganic filler is 0.1 to 30 wt% based on the total composition.
(FR) L'invention concerne une composition comprenant un polymère à base de propylène (A), un premier élastomère (B1) de comonomère d'éthylène et d'α-oléfine ayant de 4 à 10 atomes de carbone, un second élastomère (B2) de comonomère d'éthylène et d'α-oléfine ayant de 4 à 10 atomes de carbone et une charge minérale (C), le premier élastomère (B1) ayant une masse volumique de 0,850 à 0,890 g/cm3 et un indice de fluidité de 5 à 50 dg/min mesuré selon la norme ASTM D1238 en faisant appel à un poids de 2,16 kg et à une température de 190 °C, le second élastomère (B2) ayant une masse volumique de 0,850 à 0,890 g/cm3 et un indice de fluidité de 0,55 à 4 dg/min mesuré selon la norme ASTM D1238 à l'aide d'un poids de 2,16 kg et à une température de 190 °C, la quantité totale du premier élastomère (B1) et du second élastomère (B2) étant de 2 à 30 % en poids par rapport à la composition totale, la quantité de la charge minérale (C) étant de 0,1 à 30 % en poids par rapport à la composition totale.
