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.
