Thermally conductive adhesive for many applications
thermal adhesive
Thermally conductive adhesives are synthetic resins based on epoxy resins that are enriched with fillers or silicones to which fillers have also been added.
Acrylate adhesives with fillers are also used. In addition, adhesives based on polyurethane are also being developed, which are also filled with metal oxide.
Fillers for thermally conductive adhesive
Fillers such as silver or other metals achieve the best thermal conductivity values, although the adhesive also becomes electrically conductive, which is undesirable in many applications in electronics and electrical engineering.
In order to achieve thermal conductivity with electrical insulation at the same time, adhesives with ceramic or mineral fillers must be used.
Main area of application for thermally conductive adhesive
A main area of application for thermally conductive adhesives is the heat dissipation of power electronics. When bonding heat sinks, the thermal conductivity of the adhesive reduces the thermal load on the component and thus ensures that the performance of electronic components is maintained.
However, thermally conductive adhesives are also used as a casting compound for measuring sensors that are used to measure the temperature.
Compared to thermally conductive pastes, thermally conductive adhesives have the advantage that they not only dissipate a high level of thermal energy, but also ensure fixation and attachment.
