A polyurethane elastomer, e.g., for use in polyurethane mats, includes the reaction product of an isocyanate component that includes at least one isocyanate and an isocyanate-reactive component that includes (a) a first polyol component including from 40 wt % to 90 wt % of at least one polyether polyol having an average hydroxyl functionality that is greater than 2.5 and a number average molecular weight from 300 g/mol to 1,500 g/mol; (b) a second polyol component including from 2 wt % to 20 wt % of at least one ethylene oxide capped polyoxypropylene-polyoxyethylene polyol having an average hydroxyl functionality greater than 1.5 and less than 4.0, a number average molecular weight from 4,000 g/mol to 6,000 g/mol, and from 60% to 85% of a primary hydroxyl group content; and (c) a third polyol component including from 1 wt % to 20 wt % of at least one polyoxypropylene polyol having an average hydroxyl functionality greater than 1.5 and less than 4.0 and a number average molecular weight from 300 g/mol to 1,500 g/mol.
