  • Blow Molding Polymers with Improved Cycle Time, Processability, and Surface Quality
    Publication number: 20220275183
    Abstract: Ethylene-based polymers having a density of 0.952 to 0.965 g/cm3, a high load melt index (HLMI) from 5 to 25 g/10 min, a weight-average molecular weight from 275,000 to 450,000 g/mol, a number-average molecular weight from 15,000 to 40,000 g/mol, a viscosity at HLMI from 1400 to 4000 Pa-sec, and a tangent delta at 0.1 sec?1 from 0.65 to 0.98 degrees. These polymers have the processability of chromium-based resins, but with improved stress crack resistance, and can be used in large-part blow molding applications.
    Type: Application
    Filed: May 17, 2022
    Publication date: September 1, 2022
