Abstract:
Elastic bonding films that include an elastic, thermoset core layer and a thermoplastic bonding layer on each side of the core layer are described. The thermoset core layer is a polyurethane formed as the reaction product of (i) a multifunctional isocyanate with (ii) a combination of polyols comprising (a) polyester diol, (b) crosslinker, and (c) hard segment. Articles incorporating such elastic bonding films including fabrics bonded to such films are also described.
