  • Manufacture of resilient foams based on a melamine-formaldehyde condensate
    Patent number: 4334971
    Abstract: A process for the manufacture of a resilient foam based on a melamine-formaldehyde 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.
