  • Process for manufacturing foamed materials involving contacting a thin unbroken film of liquid resin with a gaseous blowing agent under pressure
    Patent number: 4120923
    Abstract: Stable foams of reaction resins and/or condensation resins can be obtained by adding a blowing agent which is gaseous under normal conditions to the resin under pressure, the gas liquid interface being enlarged while dispensing with moving equipment, allowing the mixture to expand and to cure.
