Thermal and wave-absorbing composite materials are multifunctional composites integrating dual capabilities of thermal conductivity/heat dissipation and electromagnetic wave absorption. They are mainly composed of "base material + dual-functional fillers":

Base Material: Mostly silicone, rubber, or resin (ensuring flexibility/formability);
Fillers: Two types included: ① Thermal conductive fillers (e.g., alumina, boron nitride) to construct heat transfer pathways; ② Wave-absorbing fillers (e.g., ferrite, carbonyl iron powder, graphene) to absorb electromagnetic radiation.

Their core characteristic is synergistically solving the "heat dissipation + electromagnetic interference (EMI)" challenge: they not only conduct heat from electronic components through thermal conductive fillers but also attenuate electromagnetic radiation generated by devices via wave-absorbing fillers (avoiding interference with surrounding components). Meanwhile, they possess properties such as insulation, temperature resistance (-40~150℃), and easy fitting.

Typical applications include 5G radio frequency (RF) modules, new energy vehicle electronic control systems (IGBT), millimeter-wave radar, and aerospace electronic devices — these scenarios require both thermal management and compliance with electromagnetic compatibility (EMC) requirements. The material serves as an efficient integrated solution replacing "single thermal conductive materials + separate wave-absorbing components".
