Abstract

The present disclosure relates to compositions, laminates, films and/or composites made from polymers, such as thermoplastic polyurethane (“TPU”). The films have one or more optical layers made from materials that allow the transmission of visible light and reflect or absorb UV light. A composite having an infrared (“IR”) cutoff layer, and a polymer layer desirably having an ultraviolet (“UV”) absorber is disposed between layers of glass or artificial glass, combined with polycarbonate (“PC”) or polyethylene terephalate (“PET”) layers.
