reaction of isocyanates with hydroxyl-bearing prepolymers to
make polyurethanes is mentioned above in Reaction injection
molding. These materials also can be foamed by incorporating a
volatile liquid, which evaporates under the heat of reaction and
foams the reactive mixture to a high degree. The rigidity of the
network depends on the components chosen, especially the
prepolymer. What made you want to look up "foamed thermoset"?
