Patent abstract
Foamable one-part polyurethane compositions contain a high functionality quasi-prepolymer and a hydrated salt. The foamable compositions are capable of expanding to 1000% or more of their original volume to form a low density, stable foam. The compositions are particularly useful as foam-in-place thermal or sound insulation materials, especially in vehicle applications.
