The HW9000-series thermally conductive absorbers have dual functions of wave absorption and thermal conduction. They are composite materials made of polymer and various wave absorbing fillers and additives. The product can achieve low interface thermal resistance and absorb electromagnetic waves at low pressure and has good electrical insulation and environmental stability.
HW9000-series, like the use of thermal pads, is placed between the heat source/electromagnetic wave radiation source and the heat sink to conduct heat conduction while absorbing electromagnetic waves. This product is especially suitable for the application of optical transceiver in the telecommunication industry.
