Product Description
Perfect ferroelectric relaxor composition, high dielectric constant, slim hysteresis, dielectric breakdown > 300 MV/m (Weibull), used for high energy density capacitor, electrocaloric cooling ECE or actuator
CFE content is ~7mol%, optimized composition for K>50 at 25 C and 100 Hz
Melting Temperature: 125-135 C
Young's Modulus at 20 C: 150-250 MPa
Even though the terpolymer has very high dielectric constant and great for electrostatic adhesion (electrostatic chuck, electrostatic brake) or energy storage capacitor applications, it is very soft and very difficult to handle.
This product uses a 76 um thick PET with aluminum electrode as carrier to help the use of soft high-K terpolymer. The 76 um thick PET is quite strong and serve as a carrier to minimize damage of soft terpolymer film. The aluminum on PET can serve as electrode for the terpolymer film (the aluminum is between PET and CFE).
The aluminum on PET is 1 ohm/sq, and the terpolymer coating is 3 um~10 um.
Terpolymer can be removed with acetone or MEK to expose the bottom aluminum electrode.
