Poled PVDF piezoelectric film without electrode. Thickness of 42~45 um, other thickness available upon request, high d31 >27 and d33 >20 pC/N.
Dielectric Constant ~12.9, dielectric dissipation factor ~1.9% at 22 C and 1 kHz
Young's modulus >2.6 GPa at 25 C. [Competitor's 40 um thick piezo film ~2 GPa]
Thermal shrinkage <0.6% at 65 C and 60 minutes. [Competitor's 40 um >1.3%]
For piezo sensors. loudspeakers.
This is a short roll of 350 mm wide and 50 m long, on 3" ID core. it is corona treated with surface energy higher than 50 dynes and is ready for silver screen printing.
Contact us if you need longer or wider rolls. Thermal stability [thermal shrinkage] can be improved with slight sacrifice of piezo response.
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).
