Abstract: O.Z. 0050/033,801 A process for the preparation of a resilient foam based on a melamine-formaldehyde condensate, wherein a very concentrated aqueous solution or dispersion which contains a melamine/formaldehyde precondensate, an emulsifier, a volatile blowing agent and a curing agent is foamed under conditions such that initially there is only a slight increase in viscosity and the curing process, accompanied by a large increase in viscosity, only commences when foaming has substantially ended.

Abstract: A process for the manufacture of a resilient foam based on a melamineformaldehyde condensate, wherein an aqueous or alcoholic solution or dispersion containing a melamine-formaldehyde precondensate, an emulsifier, a blowing agent and a hardener is foamed by ultra-high-frequency irradiation and the foam is hardened by crosslinking the precondensate. The foam may be employed for heat and sound insulation, and as a packaging material.
