Abstract: A display film includes a transparent glass layer having a thickness of 250 micrometers or less, or in a range from 25 to 100 micrometers. A transparent energy dissipation layer is fixed to the transparent glass layer. The transparent energy dissipation layer has a glass transition temperature of 27 degrees Celsius or less, a Tan Delta peak value of 0.5 or greater, or from 1 to 2 and a Young's Modulus (E′) greater than 0.9 MPa over a temperature range of −40 degrees Celsius to 70 degrees Celsius. In a preferred embodiment, the transparent energy dissipation layer comprises a cross-linked polyurethane layer or a cross-linked polyurethane acrylate layer.

Abstract: Various embodiments disclosed relate to a surfacing film. The surfacing film includes a base layer. The base layer includes a thermoplastic polyurethane film comprising a reaction product of a reaction mixture of a diisocyanate, a polyester polyol having a melting temperature of at least about 30° C.; and a diol chain extender. There are many reasons to use the surfacing film including easier and more cost effective manufacturing of the surfacing film by directly extruding the base layer by mixing the reaction mixture in an extruder. Another reason to use the surfacing film is that the film has improved resistance to discoloration. Another reason to use the film is that the film shows good toughness.

Abstract: A display film includes a transparent polymeric substrate layer and a transparent energy dissipation layer disposed on the transparent polymeric substrate layer. The transparent energy dissipation layer includes cross-linked polyurethane and a polyacrylate polymer. The transparent energy dissipation layer has a glass transition temperature of 27 degrees Celsius or less and a Tan Delta peak value of 0.5 or greater.
