The GPExtreme series contains silicone rubber with superior thermal conductivity 11 W/m-k. It is a specially treated high performance ceramic particle filled silicone rubber, containing an extremely conforming and thermally conductive thermal pad. The Ultrasoft and Ü bersoft versions fill voids and rugged surfaces, while efficiently transferring heat from components to the heat sink.


  • Enhanced thermal conductivity
  • Ü bersoft and Ultrasoft are highly compressible
  • Provides good wetting
  • Self-tacky or additional PSA available
  • Convenient packaging
