Membrane casting machine Membrane casting machine

The Helmholtz-Zentrum Geesthacht made machine (center of picture) allows casting of microporous support membranes onto fleece material on rolls up to 70 cm width. These support membranes are produced by a precipitation process from polymer solutions into water. They are highly porous and show an evenly smooth surface.

Membrane coating machine Membrane coating machine

This machine coats support membranes with functional thin film separation layers. These layers from silicone or PTFE can be produced in the range of 0.5 to 10 µm thickness.
