A method of making a flexible medical article or tube, for example, a sheath for a vascular access device, is provided. The method can include extruding a polymer, for example, a polycarbonate-urethane copolymer, to form a tube and annealing the extruded polymer. The method can further include cutting the extruded tube to a desired length before or after annealing, flaring one end of the annealed tube and over-molding the flared portion onto a hub, and forming the other end of the tube into a tip. A sheath formed by such a method is also provided.

Thermoplastic articles are molded from thermoplastic polyurethane compounds including blends of aromatic polycaprolactone thermoplastic polyurethane and aliphatic polycaprolactone thermoplastic polyurethane. The thermoplastic articles can have enhanced stability against exposure to ultraviolet (UV) light relative to thermoplastic articles molded from thermoplastic polyurethane compounds including only aromatic polycaprolactone thermoplastic polyurethane as the thermoplastic polyurethane component. Additionally, the thermoplastic articles can have good stain resistance, good clarity (i.e., low haze), and other desirable properties.

A hybrid-type door outside belt for a vehicle utilizes different materials for a skin layer of a skin body that is mounted to an upper end of a door panel and a main wing that is moved by contacting the door glass, the skin layer of the skin body being made of a material having excellent scratch-resistance, and the main wing being made of a material having excellent compression set (deformation).
