Abstract: A multilayered structure comprising, in sequence, an ABS layer, a foamed polyurethane layer and a constraining layer the layers adhering one to the other is disclosed. This composite structure that entails a constrained ABS layer that contains specific additives, and a foamed polyurethane layer that was foamed by 1,1,1,3,3-pentafluoropropane, is characterized by its exceptional resistance to thermal cycling and is therefore suitable for refrigeration purposes.
