Piezotech® electro-active polymers

P(VDF-TrFE) copolymers and P(VDF-TrFE-CTFE/CFE) terpolymers are produced via a unique process resulting in high purity and low volatile content. Piezotech® polymers dissolve readily into a select group of conventional solvents and can easily be processed via routine printing techniques, including screen-printing, spin coating, solvent casting, slot-die coating, ink-jet printing, and roll-to-roll processes.

Piezotech® FC

  • Low power consumption: external power source unnecessary
  • Good mechanical properties
  • Wide frequency range
  • Transparency
  • Chemical resistance
  • High dielectric strength

 

P(VDF-TrFE) resins in powder form are available in variety of VDF/TrFE ratios. These polymers exhibit high piezoelectric responses over a wide range of temperatures in their poled ferroelectric phase.

Piezotech® RT

  • High deformation (directly proportionnal to the applied electric field squared, E²)
  • High elastic energy
  • High stress

 

 

 

 

P(VDF-TrFE-CTFE) or P(VDF-TrFE-CFE) are unique relaxor ferroelectric polymers that exhibit high electrostrictive strain and high dielectric constants. Piezotech® RT terpolymer powders are available with either CFE or CTFE as the termonomer.
