Patent ID: 8283418

Claim:
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 −1 to the absorption band at 973 cm −1 (A 998 /A 973 ) below 0.10, 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.
