Thermal conductive absorbing plates are made by synergistically dispersing thermal conductive fillers (such as alumina and boron nitride) and magnetic absorbers (such as ferrite and carbonyl iron powder) in a polymer matrix. Thermal conductive fillers construct phonon transfer networks, while magnetic absorbers provide magnetic loss capability. The product is supplied in sheet form, with flexibility and surface adhesion.
The working principle is based on a dual mechanism of thermal conductivity and absorption. In terms of thermal conductivity, the fillers come into contact with each other to form a continuous thermal conduction channel, which transfers heat from the heat source to the heat dissipation end. In terms of absorption, magnetic absorbers convert electromagnetic energy into thermal energy through hysteresis loss and eddy current loss in alternating electromagnetic fields, and the absorbed electromagnetic energy can be quickly carried away by the thermal conduction path.
The product advantages are reflected in the following aspects. Dual function integration: Replace the combination of "thermal pad absorbing wave plate" with a single piece of material to save space. Adjustable thermal conductivity and absorption performance: thermal conductivity coefficient of 1.0~5.0W/m · K, absorption frequency range covering a wide frequency range. Flexible fit: can compress and fill irregular surfaces, adapting to different gap tolerances. Advanced Institute Technology supports customization of thermal conductivity, thickness, and absorption frequency band.

Raw material preparation
Thermal conductive filler treatment: Insulation thermal conductive materials such as boron nitride and aluminum oxide require surface modification to ensure uniform dispersion.
Absorbing agent processing: Magnetic materials (such as ferrites) need to be ground to the micrometer/nanometer level to avoid agglomeration and affect performance.
Slurry mixing
Mix thermal conductive fillers, absorbers, and matrix materials (silicone, polyurethane, or epoxy resin) to form a uniform slurry.
Viscosity needs to be controlled to ensure the feasibility of coating or rolling processes.
Coating/Rolling Forming
Coating method: The slurry is formed into a thin film by scraping or roller coating, suitable for thin products (0.1~0.5mm).
Rolling method: Suitable for thick or multi-layer composite structures through hot pressing molding.
Curing and post-processing
Heat curing or UV curing to shape the material and stabilize its performance.
Some products require surface coating with release film or adhesive layer to facilitate subsequent installation.
Cutting and Testing
Cut into the required size and conduct tests on thermal conductivity, absorption performance, and insulation.
The production of thermally conductive wave absorbing plates relies on precise material ratios and molding processes, and its principle is to solve heat dissipation and electromagnetic interference problems synchronously through composite structures. When using, attention should be paid to installation methods, environmental matching, and maintenance cycles to ensure long-term reliability. This type of material has key application value in the fields of 5G, new energy, and high-end electronics.
