Piezoelectric PVDF and PVDF-TrFE (80/20) film with thermal stability up to 125 C.
Regular PVDF piezo film operation temperature is 65 C, and then will shrink in d31 direction and piezo performance decreases.
This is special grade piezo film with operation/process/storage temperature up to 125 C (no performance decrease or dimension change at 125 C for one hour).
For PVDF, d33 ~10-13 pC/N, d31 >15 pC/N. Size is 200 mm x 250 mm, thickness is 30 um, 50 um, or 110 um. Other thickness can be produced based on request.
For PVDF-TrFE 80/20, d33 ~25 pC/N, d31 >15 pC/N. Size is 100 mm x 100 mm, thickness is 120um, 20 um, 12 um, or 16 um. Other thickness can be produced based on request. Dielectric constant is around 8.0 at 1 kHz and 25 C.
PVDF Dielectric Constant ~12.5~13.0, dielectric dissipation factor ~1.9% at 22 C and 1 kHz
Special grade produced based on special request.
