A display film includes a transparent cross-linked polyurethane acrylate layer. The transparent cross-linked polyurethane acrylate layer having a glass transition temperature of 10 degrees Celsius or less and a Tan Delta peak value of 0.5 or greater.

Polyurethane acrylate protective display film

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.
