POLYETHYLENE COMPOSITIONS FOR ROTATIONAL MOLDING |
摘要 |
<p>Polyethylene blend compositions suitable for rotomolding, rotomolded article s, and processes for rotomolding articles are provided. The polyethylene compositions include a first polyethylene having a melt index of 0.4 to 3.0 g/10 min and a density of from 0.910 to 0.930 g/cm3; and a second polyethyle ne having a melt index of 10 to 30 g/10 min and a density of 0.945 to 0.975 g/cm3. The composition has a density of from 0.930 to 0.955 g/cm3 and a melt index of 1.5 to 12 g/10 min, and the first and second polyethylenes differ i n density by from 0.030 to 0.048 g/cm3. These compositions exhibit improved physical properties, such as Environmental Stress Crack Resistance and Izod Impact Strength.</p> |
