Abstract
Composite film structures including a polyfluorourethane (PFU) layer are described. The PFU layer is in contact with a polymer film to form a thermoformable composite film. The composite films exhibit a low Tg and resulting shapeability allowing them to be applied to non-planar irregular surfaces. The composite achieves thermoformability in the absence of deep dip dyeing.
