Poled PVDF piezoelectric film without electrode. Thickness of 42~45 um, other thickness available upon request, high d31 > 28 pC/N and d33 >20 pC/N.
Dielectric Constant ~12.9, dielectric dissipation factor ~1.9% at 22 C and 1 kHz
Young's modulus >2.5 GPa at 25 C.
Thermal shrinkage <0.5% at 65 C and 30 minutes.
For piezo sensors. loudspeakers.
This is a short roll of 350 mm wide and 10 m long [No core used for the short roll]. It is corona treated with surface energy higher than 50 dynes and is ready for silver screen printing.
It may have a few local pinholes, but will not affect the fabrication of small sensors.
Also for electroactive polymer EAP actuator, soft actuator, robotics
Uniaxially oriented with high d31 (but almost no d32).
