Beschreibung
Zusammenfassung:	Composites comprising a polyurethane core and an outer facing layer are described in the present invention. Suitable polyurethane cores are hydrophilic polyester-polyurethane foamed materials which comprise the reaction product of: (a) at least one polyisocyanate, with (b) at least one polyester polyol containing at least two hydroxyl groups and having an average molecular weight within the range from more than 700 to 10,000, and (c) at least one ethoxylated polyether polyol, containing at least two hydroxyl groups, having a molecular weight of at more than 700, a functionality of from 2 to 6, and having a degree of ethoxylation greater than 30% by weight, and (d) optionally, at least one compound containing at least two active hydrogen atoms and having an average molecular weight within the range from 32 to 700, and (e) catalysts, water and/or foaming agents, and (f) optionally, adjuvant substances and additives. The present invention also relates to process for the production of these composite materials, and to the use of these composite materials for vehicle interior trim.
