Patent ID: 8895659

Claim:
A polypropylene composition comprising a polypropylene base resin, the polypropylene base resin having lamellas of a thickness from 24.2 nm to 84.6 nm in an amount of at least 40% when measured by stepwise isothermal segregation technique (SIST); and a molecular weight distribution broadness Mw/Mn as calculated from gel permeation chromatography according to ISO 16014-4 2003, of at least 5, and a weight average molecular weight Mw of 130,000 g/mol or lower determined by GPC according to ISO 16014-4 2003; and the polypropylene composition having an MFR 2 measured according to ISO 1133 (230° C., 2.16 kg load) of at least 50 g/10 min; and a tensile modulus of 2000 MPa or higher when measured according to ISO 527-2 using injection moulded test specimens T as described in EN ISO 1873-2 (dog bone shape, 4 mm thickness).
