摘要： Thermoplastic polyurethane compositions are disclosed, comprising: a thermoplastic polyurethane polymer or polymer blend comprising the reaction product of: an aliphatic diisocyanate, an aliphatic polyol, and a chain extending agent, wherein the thermoplastic polyurethane composition: when tested by a 25% Heat Relaxation Test at a thickness of about 0.006 inches, exhibits a final load from about 0.02 to about 0.3 pounds force; and when tested by a 25% Elastic Recovery test, exhibits a residual strain at one minute of 2% or greater.

摘要： 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.

摘要： Thermoplastic films are disclosed that include a thermoplastic polymer layer comprising a thermoplastic polyurethane polymer and a copolyester polyether 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, exhibits a final load from about 0.02 to about 0.3 pounds force; and when tested by a 25% Elastic Recovery test, exhibits a residual strain at one minute of 2% or greater.
