Beschreibung
Zusammenfassung:	The invention relates to a composite element having a layer structure with 2 mm - 20 mm metal, 10 mm - 100 mm compact polyurethane preparation and again 2 mm - 20 mm metal. The polymer preparation is obtained by reacting (a) a compound comprising at least two isocyanate groups with (b) polyetherpolyol and the polyetherpolyol (b) is a mixture that contains at least the components polyetherpolyol (b1) and polyetherpolyol (b2). The invention also relates to the use thereof and associated method.
