SolSep supplies PDMS homogeneous films of custom-made thicknesses. Also, films of other types of silicon can be made.
Information via info@solsep.com, plz add your specific need and use at an inquiry

Films are denoted as HFS-PDMS-XY. These are silicone/PDMS homogeneous-flat-sheets of custom-made thickness of approx XY millimeters. (XY refers to thickness of sheets, eg 0.3 mm, 0.6 mm, 1.0 mm).

These films can be typically used for gas permeability studies, coating of sensor heads and analytical equipment, etc... Films are carried on a PET sheet for stability and logistic issues covered with a same PET sheet. If you want to remove the PET layers you are encouraged to first cut the size you want and than peel off the PDMS. Alternatively, you may remove the top-PET first and cut.

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