  • Light stable aliphatic thermoplastic urethane elastomers and method of making same
    Patent number: 6187859
    Abstract: An improved light stable polyether/polyol based aliphatic urethane thermoplastic elastomer prepared from reacting inter alia a polyol having low terminal end unsaturation and an organic diisocyanate. The elastomer is characterized by ultra violet stabilizer being present in a range of 0.25% to 2.0% at a total concentration of 1.0% to 2.0%, an antioxidant being present at a total concentration of 0.10% to 1.0%, and colorants/pigment being present in a total concentration in a range from 1.0% to 2.05% to produce an elastomer capable of withstanding Xenon arc artificial weathering with DE≦3.00 after 2450 kilojoules of exposure.
    Type: Grant
    Filed: October 19, 1998
    Date of Patent: February 13, 2001
    Assignee: Davidson Textron Inc.
