Thermiglue thermal adhesive
Thermally conductive adhesives are epoxy-based synthetic resins enriched with fillers or silicones also enriched with fillers.
Acrylic adhesives enriched with fillers are also used.
In addition, polyurethane-based adhesives are currently being developed.
Fillers for thermally conductive adhesives
Fillers such as silver or other metals achieve the best thermal conductivity values, but the adhesive also becomes electrically conductive, which is undesirable in many applications in electronics and electrical engineering.
To achieve thermal conductivity with simultaneous electrical insulation, adhesives must be used that contain ceramic or mineral fillers.
Areas of application for thermally conductive adhesives
One of the main areas of application for thermally conductive adhesives is the heat dissipation of power electronics. When heat sinks are bonded, the thermal conductivity of the adhesive reduces the heat load on the component, thus ensuring that the performance of electronic and electrical components is maintained.
However, thermally conductive adhesives are also used as potting compounds for measurement sensors that are used to measure temperature. Thermal conductive adhesives are also increasingly used in batteries.
Compared to thermally conductive pastes, thermally conductive adhesives have the advantage that they not only dissipate a high level of thermal energy, but also provide fixation and fastening at the same time.
