  • PREPARATION OF THIN-WALLED ARTICLES OF POLYURETHANEUREA
    Publication number: 20090055994
    Abstract: Certain polyether- or polyester-based polyurethaneureas in dipping solutions of organic solvent at a concentration of, for example, 12 to 20%, are particularly suited for use in a mandrel-dipping process for producing thin-walled elastic articles, such as surgical gloves. Such dipping solutions can be easily prepared, for example, by dissolving yarn comprising the polyurethaneurea and without the need to utilize metal chlorides, such as lithium chloride, in the yarn dissolving procedure.
