摘要
The present disclosure provides a polyolefin-based composition made from or containing: (A) a first polymer composition made from or containing a high density polyethylene having a density greater than about 0.940 grams per cubic centimeter and a melt index greater than about 4 grams per 10 minutes, measured according to ASTM D 1238, using a piston load of 2.16 kg and at a temperature of 190 degrees Celsius, and (B) a first nucleator composition made from or containing a salt of 4-(4-chlorobenzoylamino) benzoate. The polyolefin-based composition is useful for making articles of manufacture for rigid applications, including low temperature, thin-walled applications.
