    摘要: The invention provides a heterophasic propylene polymer composition comprising the following components:

    i) 60 to 90% wt, relative to the total weight of components i), ii) and iii), of a propylene polymer matrix comprising at least one propylene polymer and having an ethylene content of no more than 5% wt;
    ii) 5 to 30% wt, relative to the total weight of components i), ii) and iii), of an elastomer; and
    iii) 5 to 25% wt, relative to the total weight of components i), ii) and iii), of an ethylene copolymer plastomer having a density of not more than 910 kg/m 3 and a melt flow rate MFR 2.16 (190°C) of at least 0.5 g/10 minutes at 190°C under a weight of 2.16 kg.
