Biaxially oriented PVDF-HFP film with thickness from 2 um to 10 um. High dielectric constant >12, High Dielectric Breakdown Strength > 600 MV/m. Great for high energy density film capacitors and piezo film
The biaxial orientation significantly improved the dielectric breakdown strength (energy density) and reduced the leakage current and energy loss.
This film is NOT poled and it is non-piezoelectric. But the customer can pole the film by themselves.
