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).
