Abstract
Moldings made from foam plastic having an integrated covering of a laminate having a layer of certain copolyether esters. These are, in particular, foam-molded mattresses and cushions for furniture and vehicles, in particular car seats. Compared with the corresponding known moldings, having a polyurethane layer, they are distinguished by lower processing shrinkage and good bonding of the copolyether ester layer to the polyurethane core.
