Abstract
Polyethylene blend compositions suitable for injection molding, injection molded articles, and processes for injection molding articles are provided. The polyethylene compositions include a first polyethylene having a melt index of 0.1 to 3.0 g/10 min and a density of from 0.905 to 0.938 g/cm; and a second polyethylene having a melt index of 10 to 500 g/10 min and a density of 0.945 to 0.975 g/cm. The composition has a density of from 0.920 to 0.973 g/cmand a melt index of 2 to 200 g/10 min, and the density of the second polyethylene is from 0.037 to 0.062 g/cmgreater than the density of the first polyethylene. These compositions exhibit improved physical properties, such as Environmental Stress Crack Resistance, relative to conventional compositions of similar melt index and density.
