Abstract: Described herein is a process for producing polyurethane sandwich moldings including at least one core layer and at least one reinforcing fiber layer, where (i) at least one reinforcing fiber layer is applied onto a core layer and a moisture-curing polyurethane adhesive is applied to a reinforcing fiber layer, (ii) the part from (i) is placed into a mold and pressed in the mold and the moisture-curing polyurethane adhesive is cured, and (iii) the molding from (ii) is removed from the mold and optionally subjected to further operations, where the moisture-curing polyurethane adhesive is applied before or after application of the reinforcing fiber layer onto the at least one core layer and for the curing the moisture-curing polyurethane adhesive is brought into contact with water or with a solution comprising water. Also described herein are a polyurethane sandwich molding obtainable by such a process and a method of using a polyurethane sandwich molding in vehicles.

Abstract: Sound-damping and energy-absorbing flexible PUR foams are produced by reacting organic and/or modified organic polyisocyanates (a) with a polyetherol mixture (b) and, if desired, further compounds (c) bearing hydrogen atoms which are reactive toward isocyanates, in the presence of water and/or other blowing agents (d), catalysts (e) and, if desired, further auxiliaries and additives (f).

Abstract: Flame-resistant flexible polyurethane foams are produced by reactinga) organic and/or modified organic polyisocyanates,b) relatively high molecular weight compounds containing at least two reactive hydrogen atoms andc) if desired, low molecular weight chain extendersin the presence ofd) catalysts,e) blowing agentsf) flame retardants,and, if desiredg) auxiliaries and/or additives,where the flame retardants f) used are melamine in combination with at least one anionic dispersant.
