Abstract: The invention relates to a component having at least to some extent a layer structure, wherein the layer structure includes an elastomer layer with a density greater than 800 g/L, and a thermoset layer including at least 50% by weight of a first polyurethane. The invention further relates to a process for the production of a component of this type, the process including (i) provision of a female mold into which the individual layers of the layer structure are introduced, or of a male mold to which the individual layers of the layer structure are applied; (ii) production of the elastomer layer via spraying; (iii) production of the thermoset layer via spraying; and (iv) demolding of the resultant component. Step (ii) can be carried out before step (iii) or step (iii) can be carried out before step (ii).

Abstract: In a process for the production of pore-free polyurethane elastomer moldings with Shore D hardness of at least 60 in accordance with DIN 53505, (a) polyesterdiol with OH number from 20 to 100 mg KOH/g and (b) a chain extender composed of diol with molar mass below 300 g/mol, is mixed with (c) isocyanate prepolymers obtainable via reaction of diisocyanate with polyesterols with functionality from 1.95 to 2.2 and with OH number from 20 to 200 mg KOH/g to form a reaction mixture. The reaction mixture is charged to a mold and hardened to form the polyurethane elastomer. Polyurethane elastomer moldings are thus obtainable by this process, and these polyurethane moldings may be used as cladding component for commercial vehicles, bodywork component in vehicle construction, or a cladding component of a machine installation.
