  • Patent number: 5182058
    Abstract: A method of making a foamed polymer article by injection molding, using a foaming agent that evolves minimal water and does not form byproducts which could pit or chalk the polymer surface. The foaming agent contains sodium borohydride in an amount from 0.01 weight percent of the polymer to be foamed, and a polyhydric alcohol such as six-carbon mannitor as an activator to react with the sodium borohydride and produce hydrogen gas. Boric acid can be included with the alcohol. the sodium borohydride is kept separated from the other reactive components such as by encapsulation until gas production is desired when the polymer is heated and molded.

  • Patent number: 5155139
    Abstract: A method of making a foamed polymer article by injection molding, using a foaming agent that does not form byproducts which could pit or chalk the polymer surface. The foaming agent contains sodium borohydride in an amount from 0.01 to 5.0 weight percent of the polymer, and sodium dihydrogen phosphate as an activator to react with the sodium borohydride and produce hydrogen gas. The sodium borohydride and the sodium dihydrogen phosphate are kept separated from direct contact with each other, such as by encapsulating the components, until gas production is desired when the polymer is heated.
