An isocyanate-reactive composition is provided which comprises:

Isocyanate-reactive compositions containing internal mold release agents

An open-celled polyurethane foam is provided having a density of 1.5 to 5.0 pcf, a G value of 30 to 80 over a static load range of 1.0 to 2.0 psi based on a 2.0 inch thickness and a 24 inch drop height and, an airflow in the range of 0.05 to 0.5 scfm, 25% as compressive strength of 4.0 psi or more prepared by a process comprising reacting, under foam forming conditions:

Energy absorbing polyurethane foams

Microcellular polyurethane elastomers having nonpeelable skin surfaces having densities ranging from 0.1-1.1 gm/cm.sup.3 can be made from conventionally employed reactants using carbon dioxide gas as the sole source of blowing agent resulting from the H.sub.2 O/-NCO reaction when carried out in an admixture with nonhydratable particulate inorganic salts.
