Abstract
An improved process for producing a molded microcellular elastomer with a reduced number of voids from at least two liquid reactants and a gas, which process comprises introducing into at least one reactant a gas to form an admixture; passing the admixture through a static mixer at superatmospheric pressure; then immediately mixing the admixture with the other reactant at superatmospheric pressure to form a reaction mixture; introducing the reaction mixture into a mold in which the pressure is substantially below the superatmospheric pressures used above; and curing the reaction mixture in the mold to produce a molded microcellular elastomer with a reduced number of large voids.
