"A thermal interface material (often abbreviated as TIM ) is any material that is inserted between two components in order to enhance the thermal coupling between them. A common use is heat dissipation, in which the TIM is inserted between a heat-producing device (e.g. an integrated circuit) and a heat-dissipating device (e.g. a heat sink). At each interface, a thermal resistance exists and impedes heat dissipation. In addition, the electronic performance and device lifetime … " - Tim thermal conductivity
