Polydimethylsiloxane (PDMS) is a material that is often used for membranes. In literature, PDMS is used as a "container word" that suggest an well-defined material. But in fact PDMS is there in many variants, dependent on manufacturer, and slightly different tuned for a certain purpose.

SolSep produces silicone membranes including PDMS membranes. For nanofiltration, pervaporation or even gas exchange, have there base variant which is denoted as NF030105.

PDMS type membranes for nanofiltration and pervaporation are denoted as NF030105, see our datasheet section.

PDMS is also used as homogeneous thin films. These are discussed here...
