More power and light weight. In the past, these two characteristics in electronics were mutually exclusive. Now, micro-electronics are just that, and in addition, need thermal management components to further complement these objectives.

SARCON ® is an advanced silicone rubber with high thermal conductivity and superior flame-retardancy. By combining the inherent silicone rubber properties of heat resistance, electrical insulation and long-term aging into one compound, this universally applicable material can be made in an unlimited number of thermal management configurations.

UL File Number: E58126

Applications:

  • Thermal conductive insulators for semiconductors
  • Compression jointing materials for thermistors and temperature sensors
  • Thermal conductive material for all types of heaters
