In wave-power generators, NEXIPAL® can be used as an electroactive polymer to harvest energy from the sea. In this application, NEXIPAL® ensures continuous operation over millions of cycles. As a constituent of NEXIPAL ®, ELASTOSIL® can also serve on its own as a dielectric medium, return spring and carrier for electrodes. In this case, the electrodes are mounted by customers themselves. ELASTOSIL® Film is produced from addition-curing silicone rubber grades and is available in thicknesses as low as 10 micrometers.

Production takes place under clean room conditions and yields flawless, homogeneous films of extremely consistent thickness, and all contributing the positive properties of silicones.

Advantages of NEXIPAL® and ELASTOSIL ® Film

  • Continuous operation over millions of cycles
  • Constant permittivity
  • Good dielectric properties
  • High stretch recovery
  • Permanent elasticity
  • Thicknesses of individual permittivity layers between 10 and 400 micrometers
  • Outstanding precision of +/-5%
  • Flexibility at low temperatures
  • High heat resistance
