Abstract:
Bimodal polypropylene compositions and a process to form melt blended bimodal polypropylene compositions comprising combining at least two polypropylenes in at least a two-pass process, and forming a bimodal polypropylene composition having a Flexural Modulus (190° C., 1% secant) of at least 1700 MPa, as well as one or more other selected properties. These compositions are suitable for thermoformed articles and injection molded articles, any of which may be foamed.
