Incidentally, dicarbamates are produced by project partner Fraunhofer Umsicht using a high-pressure process. At a pressure of 50 bar, methanol and CO2 are synthesized with diamines to produce dicarbamates. At the same time, the Fraunhofer Institute for Chemical Technology (ICT) is developing possible recycling processes for used polyurethanes, for example from old foams, which can then be reprocessed into new PUR products. In this way, the project partners are making a contribution to establishing a more sustainable and, as far as possible, closed-loop economy in this area without greenhouse gas emissions. Incidentally, the Fraunhofer researchers have set their sights on the production of biocompatible catheter tubes for medical technology (image) as their first application. The Fraunhofer IFAM is using the variable modular system for the development of adhesives to attach cannulas to the tubing.
