The present invention relates to water-blown integral skin polyurethane foam compositions, molds polyurethane articles, a process of preparing said articles, and an isocyanate composition for use therein. In particular, the invention relates to water-blown integral skin molded polyurethane articles having particularly advantageous physical properties, and a composition useful for producing such articles. In particular, the invention provides a polyurethane composition which has an isocyanate component (a) an isocyanate reactive component (b), a blowing agent comprising water (c), a polyether (d) selected from the group consisting of polyetrahydrofuran and polyethylene glycol having a number average molecular weight of from 200 to 2000 and optionally, one or more additives (e) from the group consisting of catalysts, chain extenders, oxo alcohols, and mixtures thereof. The composition may be characterized in that integral skin polyurethane articles made of the composition have a tensile strength of greater than or equal to 450 psi and/or a Taber abrasion (mg loss) of less than 200.
