  • Patent number: 11661501
    Abstract: Bimodal high-density polyethylene polymer compositions with increased high melt strength and good processability. The compositions comprise a base resin having a density of about 945 kg/m3 to about 955 kg/m3, and an ethylene polymer (A) having a density of at least about 968 kg/m3, in an amount ranging from 45% to 55% by weight and an ethylene polymer (B) having a density lower than the density of polymer (A). The composition has a complex viscosity at a shear rate of 0.01 rad/s ranging from about 200 to 450 kPa·s and a complex viscosity at a shear rate of 100 rad/s ranging from about 1900 to 2500 Pa·s. Articles made from these compositions, such as pipes and fittings achieve long-term oxidative resistance and have a low wall thickness variability while maintaining high production output.
    Type: Grant
