Abstract: A polyurethane elastomer obtained by reacting at the least a di, tri or polyisocyanate, a polycarbonate diol and a di, tri or polyalcohol characterized in, that said polycarbonate diol is at least one polycarbonate diol of a 2-alkyl-1,3-propanediol, a 2,2-dialkyl-1,3-propanediol, an alkoxylated 2-alkyl-1,3-propanediol and/or an aldoxylated 2,2-dialkyl-1,3-propanediol and/or is at least one polycarbonate diol comprising units from two or more said 1,3-propanediols, wherein alkyl is a linear or branched aliphatic alkanyl having 1-8 carbon atoms and alkoxylated is ethoxylated, propoxylated and/or butoxylated having 1-20 alkoxy units.
