Electro Active Polymers

Solvene® EAP is a family of ferroelectric polymers and ferrorelaxor polymers which combines excellent electro mechanical properties with easy processing.

  • Solvene® 200, solvene® 250 and solvene® 300 P(VDF-TrFE) copolymers are inherently piezo-, pyro- and ferroelectric, enabling applications such as printed memories, sensors, actuators, loudspeaker, acoustic transducers, energy harvesting devices.
  • Solvene® T P(VDF-TrFE-CTFE) terpolymer is a ferrorelaxor polymer which has a high dielectric constant. It is ideal for high strain actuators with low applied voltages.
  • Solvene® T XL in PGMEA, crosslinkable high dielectric constant grade for multilayer, high speed deposition.

Key Features

Solvene® copolymers:

  • Transparent
  • d33 > = –22pC/N
  • Curie Temperature: up to 133 °C

Solvene® T terpolymers:

  • Transparent
  • Dielectric constant k @1 KHz, 23 °C, > 45
  • Breakdown voltage > 300 V/µm

Solvene® T XL in PGMEA

  • Transparent and colorless after XL
  • Dielectric constant KR1 KHz, 23 °C, ≃ 12-16
  • Flexible and printablwe


Solvene® materials can be processed by applying various techniques, from classic extrusion to different printing techniques on various substrates which include flexible plastic films or paper.

Solvene® polymers are available in powder form or as ready-to-process formulations.
