Casting process for flat membranes

Roll-to-roll production

Using a roll-to-roll process, we can produce flat membranes with thicknesses between 20 and 200 µm and a width of 300 mm. 

During casting, both temperature and atmosphere can be controlled and we have a precipitation bath which allows temperatures between 4 and 90°C. 

 

Dense, multilayer and mixed-matrix membranes

The main focus of Fraunhofer IGB is the processing of mixed-matrix systems. Using solvent evaporation or phase inversion processes, we can also produce both dense and porous membranes. In addition, we can calender multiple functional layers to form complex systems.
