Abstract: The present invention relates to a polyurethane, in particular a thermoplastic polyurethane, obtainable or obtained by reacting at least the components (i) to (ii): (i) a polyisocyanate composition; (ii) a polyol composition, comprising (ii.1) at least one polyester diol or polyether diol having a number-average molecular weight in the range from 500 to 3000 g/mol, (ii.2) at least one polysiloxane having two terminal isocyanate-reactive functionalities selected from the group consisting of thio group, hydroxyl group and amino group. The invention additionally relates to a process for preparing this polyurethane, to the use thereof, to a molded body comprising the polyurethane. Furthermore, the invention relates to foam beads based on polyurethane, obtained or obtainable from the polyurethane, to a process for producing foam beads and also to bead foams and to the use thereof.
