Abstract
The invention relates to propylene polymer compositions comprising 50-70 wt % of a propylene homo- or copolymer, 5-20 wt % of a first elastomeric ethylene-propylene copolymer, 5-25 wt % of a second elastomeric ethylene-propylene copolymer and 5-30 wt % of an ethylene polymer. The propylene polymer compositions are suitable for molding and they have low haze and a good impact strength/stiffness balance with good impact strengths at low temperatures.
