Perfect ferroelectric relaxor composition, high dielectric constant, slim hysteresis, dielectric breakdown > 300 MV/m, used for high energy density capacitor, electrocaloric cooling ECE or actuator

CTFE content is 7~9mol%, optimized composition for K>45 at 25 C and 100 Hz

Melting Temperature: 125-135 C

Young's Modulus at 20 C: 150-250 MPa

Size 200 mm x 270 mm. Maybe on metallized PET film, the aluminum on PET is 1 ohm/sq, and the terpolymer coating is 3 um. Terpolymer can be removed with acetone or MEK to expose the bottom aluminum electrode.

Metallized PET is 50.8 um thick.
