Gas Permeable PDMS Membranes

Thin polydimethylsiloxane (PDMS) membrane products which can be used as a barrier to liquid and permeable path for various gaseous elements and compounds.

Product Description

Gas Permeable PDMS Membranes

Gas Permeable PDMS Membranes are thin silicone or polydimethylsiloxane (PDMS) membrane products which can be used as a barrier to liquid and permeable path for various gaseous elements and compounds.

We supply these silicone membranes in sheets or rolls from as thin as 0.075mm (0.003″) to 1mm (0.040″) thick. Sheets are 300mm (12″) square.

This material can be modified to produce thin film parts, or combines with many other materials to produce composite materials specific to your requirements.
