  • Barrier layer in between polyurethane foam and vinyl skin
    Patent number: 4952447
    Abstract: A vinyl-skin-covered polyurethane-foamed article is disclosed, comprising a polyurethane foam core, a vinyl skin covering the polyurethane foam core, and a barrier layer between the polyurethane foam core and the vinyl skin that reduces the migration of polyurethane foam components into the vinyl skin and reduces the migration of vinyl skin components into the polyurethane foam core. In a particularly preferred embodiment the barrier layer comprises cellulose acetate or cellulose acetate butyrate. The barrier layer reduces or eliminates the action of vinyl skin components on polyurethane foam and the action of polyurethane foam components on vinyl skin without degrading the physical properties of either the vinyl skin or the foam.
