  • Process and apparatus for producing foam
    Patent number: 6572800
    Abstract: CO2 is used as the blowing agent, and a first and second control agents are injected into the melt, the first control agent being designed to dissolve and cool the melt and consisting of ethanol, while the second control agent is only designed to cool the melt and consists of H2O2, the injected amount of ethanol being just sufficient for achieving the highest possible dissolution of CO2 in the melt and the injected amount of H2O2 being such that the foaming produced by ethanol is minimized. The apparatus includes arrangements for conditioning and feeding the blowing agent and control agents into the melt. The blocks and boards exhibit dimensional stability and good self-extinction features.
