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.

This terpolymer has high dielectric constant without adding any inorganic particles, therefore its dielectric breakdown strength is high. It is also flexible and soft.

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

Film is 200 mm wide, sell in 1 m, 5 m, or 10 m length.

On PET release film [can be easily peel off]

contact us for large order >10 m or other thickness.

Special thickness/width production with lead time of 1 week.

Thickness ~4 um, ~10 um, 20 um, 30 um, and 40 um. Non-oriented

Relaxor Ferroelectric Ferrorelaxor Terpolymer

The solution for film casting was filtered with 0.5 um filter and dielectric breakdown is higher than 300 V/um for 5 mm size sample.
