Abstract

The invention relates to the use of a one-component moisture-curable polyurethane hot-melt adhesive to adhesively bond plasticizer-containing substrates, comprising at least one moisture-curable polyurethane polymer P obtainable by the reaction of at least one isocyanate-functional species A and at least one polyester polyol B. The moisture-curable polyurethane hot-melt adhesive exhibits improved stability against plasticizer migration is particularly suitable for use in interior automotive assembly, as a laminating adhesive or for the building of sandwich elements.
