  • Publication number: 20190263034
    Abstract: Provided herein is a system for producing a foamed polymer. The system comprises a first mixer for mixing at least two mutually reactive reaction components to obtain a reaction mixture that reacts to afford a polymer. At least one of the reaction components further comprises a supercritical fluid. The system further comprises a foaming mold for receiving the reaction mixture which is connected to the first mixer and has a first volume available for receiving the reaction mixture. The first volume is variable. Also provided herein is a process for producing a foamed polymer.
