Piezo-electric Materials

We stock a range of poled and un-poled PVdF film which can be supplied uncoated or metalised on one or both sides for electrical connections. The electrode coating is typically Chrome-Gold (CrAu). Options of Platinum-Gold (PtAu) and Platinum-Silver (PtAg) are available.

All films can be supplied without electrode coatings. Alternatively they can be supplied with one or both sides having sputtered metal electrodes.
