  • Froth process for continous manufacture of polyurethane foam slab-stocks
    Patent number: 5665287
    Abstract: A process and a system for the continuous manufacture of polymeric foams. Reactive chemical components and additives comprising a low boiling blowing agent are mixed under pressure; the mixture is then frothed before chemical reaction takes place by feeding the mixture through a pressure equalizing and frothing device comprising a pressure-drop zone opening into a frothing cavity having an output aperture to discharge the froth onto a moving substrate.
    Type: Grant
