Beschreibung
Zusammenfassung:	Polyethylene formulations, articles produced therefrom, and methods of making articles are provided. The polyethylene formulation includes a multimodal high density polyethylene (HDPE) composition, and 1 ppm to 10,000 ppm of a nucleating agent, wherein the multimodal HDPE composition comprises a density of 0.940 g/cm3 to 0.970 g/cm3 when measured according to ASTM D792, and a melt index (I2) of 0.01 g/10 min. to 1.0 g/10 min. when measured according to ASTM D1238 at 190° C. and a 2.16 kg load, and wherein the multimodal HDPE composition comprises an infrared cumulative detector fraction (CDFIR) of greater than 0.27 and an infrared cumulative detector fraction to light scattering cumulative detector fraction ratio (CDFIR/CDFLS) from 0.7 to 2.0.
