Abstract:
High melt strength polypropylene composition, wherein the high melt strength polypropylene composition comprises a high melt strength polypropylene, wherein the high melt strength polypropylene composition has a melt strength ≥45 cN, more preferably ≥50 cN, more preferably ≥55 cN, even more preferably ≥60 cN, even more preferably ≥65 cN, wherein the melt strength is determined in accordance with ISO 16790:2005 at a temperature of 200° C., using a cylindrical capillary having a length of 20 mm and a width of 2 mm, a starting velocity v0 of 9.8 mm/s and an acceleration of 6 mm/s2 and wherein the high melt strength polypropylene composition has a melt flow rate ≥1.0 and ≤4.0 g/10 min as determined in accordance with ASTM D1238 (2013) at a temperature of 230° C. under a load of 2.16 kg.
