Direct replacement for EVA can be hard to find but Cybright polyolefin encapsulants are ready to meet the challenge with improved performance. Cybright encapsulants are available in transparent, UV cut-off, plus reflective white for single and dual glass constructions.

Cybright POE encapsulants offer key properties unmatched by EVA encapsulants:


  • Higher Volume Resistivity
  • Lower Water Vapor Transmission Rate
  • Improved PID Resistance
  • Chemical inertness – no acid gas related corrosion
  • Improved thermo-mechanical properties

Under Development

  • Light Conversion Cybright POE-U
  • Thermoplastic Cybright TPO
  • Cybright EVA
