  • Patent number: 10626248
    Abstract: A flexible tube includes a polymer composition of a poly vinyl chloride having a molecular weight greater than about 1.0 inherent viscosity (IV) and a bio-based plasticizer. Further, a method of forming a flexible tube is provided. The method includes compounding a poly vinyl chloride having a molecular weight greater than about 1.0 inherent viscosity (IV) with a bio-based plasticizer to form a polymer composition and extruding the polymer composition into the flexible tube.
