摘要: The invention relates to propylene polymer blends comprising 70-92 wt % of a propylene homopolymer, 5-15 wt % of an elastomeric ethylene-propylene copolymer, 3-15 wt % of a linear low density polyethylene and an a-nucleating agent. The propylene polymer blends have an excellent impact strength/stiffness balance and optical properties. They are especially suitable for thermoforming and extrusion blow moulding.

摘要: 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 moulding and they have low haze and a good impact strength/stiffness balance with good impact strengths at low temperatures.
