Abstract
Heterophasic polypropylene composition having an MFR(2.16 kg, 230° C.) of 3.0 to 7.0 g/10 min, determined according to ISO 1 133, and a Vicat A50 softening temperature of more than 110° C. measured according to DIN EN ISO 306 at 10 N on an injection molded test specimen with the dimensions of 80×10×4 mmand a heat rate of 50° C./h including a propylene random copolymer matrix phase (A), and an ethylene-propylene copolymer rubber phase (B) dispersed within the matrix phase, wherein the heterophasic polypropylene composition has a fraction soluble in p-xylene at 23° C. (XCS fraction), and a fraction insoluble in p-xylene at 23° C. (XCU fraction), said heterophasic polypropylene composition having a tensile modulus of 450 to 850 MPa when measured according to ISO 527-2 at 23° C. temperature with an elongation rate of 1 mm/min on injection molded test specimens type 1A prepared according to ISO 1873-2; and a normalized maleic anhydride index IMA equal to or less than 0.036 μm.
