Title (EN) POLYPROPYLENE COMPOSITION (C) WITH LOW COEFFICIENT OF THERMAL EXPANSION (CLTE)
(FR) COMPOSITION DE POLYPROPYLÈNE (C) À FAIBLE COEFFICIENT DE DILATATION THERMIQUE (CLTE)
Abstract:
(EN) The present invention is directed to a polypropylene composition (C) comprising: (i) 48 to 76 wt.-%, based on the weight of the polypropylene composition (C), of a random propylene copolymer (RPP) with a melt flow rate MFR2 (230 °C) measured according to ISO 1133 in the range of 0.01 to 2.0 g/lOmin; and (ii) 23 to 50 wt.-%, based on the weight of the polypropylene composition (C), of a fibre (FB); and (iii) 0.1 to 10 wt.-%, based on the weight of the polypropylene composition (C), of a modified polypropylene (PMP); wherein (a) the random propylene copolymer (RPP) comprises polypropylene (PP1), polypropylene (PP2) and polypropylene (PP3); (b) the polypropylene (PP1) has a melt flow rate MFR2 (230 °C) measured according to ISO 1133 in the range of 0.1 to 3.0 g/10min; (c) the polypropylene (PP3) has a lower melt flow rate compared to the polypropylene (PP2) and the polypropylene (PP2) has a lower melt flow rate compared to the polypropylene (PP1). The present invention also is directed to a pipe comprising the polypropylene composition (C) and the use of the polypropylene composition (C) to lower the coefficient of linear thermal extension (CLTE).
(FR) La présente invention concerne une composition de polypropylène (C) comprenant : (i) 48 à 76 % en poids sur la base du poids de la composition de polypropylène (C), d'un copolymère de propylène aléatoire (RPP) ayant un indice de fluidité MFR2 (230 °C) mesuré selon la norme ISO 1133 dans la plage de 0,01 à 2,0 g/10 min; et (ii) 23 à 50 % en poids sur la base du poids de la composition de polypropylène (C), d'une fibre (FB); et (iii) 0,1 à 10 % en poids sur la base du poids de la composition de polypropylène (C), d'un polypropylène modifié (PMP) ; (a) le copolymère de propylène aléatoire (RPP) comprenant du polypropylène (PP1), du polypropylène (PP2) et du polypropylène (PP3) ; (b) le polypropylène (PP1) ayant un indice de fluidité MFR2 (230 °C) mesuré selon la norme ISO 1133 dans la plage de 0,1 à 3,0 g/10 min ; (c) le polypropylène (PP3) présentant un indice de fluidité inférieur par rapport au polypropylène (PP2) et le polypropylène (PP2) présentant un indice de fluidité inférieur par rapport au polypropylène (PP1) La présente invention concerne également un tuyau comprenant la composition de polypropylène (C) et l'utilisation de la composition de polypropylène (C) pour abaisser le coefficient d'extension thermique linéaire (CLTE).
