The polyurethane is obtainable by reaction of i) a polyol component, ii) an isocyanate component, and iii) a component containing at least one crosslinker. The polyol component is composed of mutually different structural units having the general formula —O—R—X—R—O— in which all of Rand Rindependently of one another are identical or different and are linear or branched C-Calkylene groups. Groups X are identical or different and are selected from bond, O, C(O)—O, and O—C(O)—O. At least 70 wt % of the structural units meet the following criteria: a) at least 80% of X are O—C(O)—O and the remainder are O or C(O)—O, and b) the average chain length of Rand Ris 8 or more carbon atoms, and c) at least 50% of Rand Rare independently of one another a linear or branched C-Calkylene group.
