  • FILMS COMPRISING ALIPHATIC THERMOPLASTIC POLYURETHANES THAT ARE USEFUL AS AUTO WRAPS
    Publication number: 20240392081
    Abstract: Thermoplastic films are disclosed that are suitable for use as auto wraps. The films include a thermoplastic polyurethane layer comprising a thermoplastic polyurethane polymer and a patterned adhesive layer. The thermoplastic films, when tested by a 25% Heat Relaxation Test at a thickness of about 0.006 inches, exhibit a final load from about 0.02 to about 0.3 pounds force; and when tested by a 25% Elastic Recovery test, exhibit a residual strain at one minute of 2% or greater.
    Type: Application
    Filed: August 25, 2022
