MANUFACTURE OF MICROPOROUS POLYURETHANE ELASTOMER PRODUCT, AND CLOSED-CELL MICROPOROUS POLYUETHANE ELASTOMER AND ISOCYANATE-REACTIVE COMPOSITION

摘要

Microcellular polyurethane elastomers having nonpeelable skin surfaces having densities ranging from 0.1-1.1 gm/cm<3> can be made from conventionally employed reactants using carbon diioxide gas as the sole source of blowing agent resulting from the H2O/-NCO reaction when carried out in an admixture with nonhydratable particulate inorganic salts.
