Thermal Conductive Silicone Rubber

HTV thermal conductive silicone rubber (heat transfer silicones) are a group of silicones that take heat from the heating part and transfer it to the cooling system, and this process facilitates the cooling process in Heatsinks. In fact, this class of silicones are designed in such a way that they have high electrical insulation properties as well as high heat transfer.

Feature of Thermal Conductive Silicone Rubber

  • High thermal conductivity
  • It has high electrical insulation properties
  • Good thermal resistance
  • Low volatility percentage
  • Flame resistant

Applications of Thermal Conductive

  • Heat transfer pad, silicone plate
  • For heat transfer in CPU, transformer, transistor pads
  • Heat conduction parts
