What Is a Thermally Conductive Adhesive?
Thermally conductive adhesive is designed to facilitate efficient heat transfer. This adhesive consists of a resin that provides the necessary adhesion strength and durability, a filler that enhances thermal conductivity, and additives that optimize performance and ease of application. Mixing disperses the thermally conductive filler throughout the resin, creating paths for thermal conduction. Upon curing, the filler and resin bond closely together, resulting in an adhesive film that boasts high thermal conductivity.
It finds critical applications across various sectors including electronics, automotive, medical devices, household appliances, and LED lighting. Uses include bonding heat sinks to CPUs, attaching engine components, affixing artificial joints, heaters, and cooling devices, and securing LED chips to substrates. The defining characteristics of thermally conductive adhesive are its excellent thermal conductivity, strong adhesion strength, and resistance to high temperatures, making it indispensable in applications requiring efficient heat management.
