Tek-Sil® SA Materials
  • Formulated to provide clean release from most surfaces
  • Material is rigid enough to be easily die cut
  • Gap filler can be readily repositioned


Tek-Sil® SA is an unsupported, thermally conductive silicone rubber with high dielectric strength to protect against power surges.  Tek-Sil® SA conforms better than many thermally conductive materials while protecting assemblies from mechancial shock and absorbing thermal expansion
