  • Gel Extruded Articles With Molecular Weight Retention
    Publication number: 20240043658
    Abstract: A polymer composition is disclosed that is particularly formulated for producing gel extruded articles containing a high density polyethylene polymer. In one embodiment, the polymer composition is used to produce a porous membrane or film well suited for use as an ion separator in an electronic device, such as a battery. The polymer composition contains a molecular weight retention package that preserves the molecular weight of the polyethylene polymer during extrusion.

  • Polymer Composition Blend and Membranes Made Therefrom
    Publication number: 20230303811
    Abstract: A polymer composition for producing gel extruded articles is described. The polymer composition contains at least three different polyethylene polymers, namely a lower molecular weight polyethylene polymer, a mid-range molecular weight polyethylene polymer, and a high molecular weight polyethylene polymer. Combining the different polyethylene polymers in different ratios can optimize not only mechanical properties but improve processing.
