Chemically blown polyurethane elastomeric closed cell foams which exhibit physical characteristics similar to those of neoprene foams are disclosed. The foams are prepared by blending a diisocyanate or polyisocyanate prepolymer, a polyol, such as a polyether polyol or polyester polyol, an amine catalyst, a chemical blowing agent, and optionally a C_2-10 diol such as butanediol, and allowing the compounds to cure to form a polymeric material. The polymer is initially heated to a temperature at or above its softening temperature, but below the temperature at which the blowing agent becomes activated, to soften the polymer. The softened polymer is then heated to a temperature at which the blowing agent is activated. The resulting polymer foam includes closed cells, but has less rigidity than conventional closed cell foams.
