Abstract:
1. Article selected from the group consisting of a refrigerator, a dishwasher and a washing machine wherein the article comprises a polypropylene composition having a reduced surface energy, comprising: a mixture of: (a) an isotactic polypropylene (iPP) produced in the presence of a single site metallocane catalyst having a molecular weight distribution (MWD) of below 4.00 and a mean isotactic block length between two structural chain defects, as a statistical average, greater than 70, and b) an atactic polypropylene (aPP) with an absorbance ratio of the absorption band at 998 cm wherein the weight ratio of said atactic polypropylene to the sum of said atactic polypropylene and said isotactic polypropylene (aPP/(aPP+iPP)) is 0.50 to 9.00 wt.-%, and wherein the polypropylene composition has surface energy of between 23.88 and 27 mN/m.
