Phase-Change Materials (PCM), Thermal Interface Material

Phase-change materials (PCM) absorbs or releases a large amount of heat when they go through a physical state change - e.g. from solid to liquid.

During heat absorption or release, the PCM's temperature remains constant. Heat absorbed by the PCM is stored therein.

PCM's ability to store and release heat in a controlled way is utilised to improve thermal performances in many applications.

PCMs are applied like thermal pads. On reaching their melting point, they change to a half-liquid state - eliminating air gaps and maximising heat dissipation.

PCMs are usually sticky and often used in place of thermal pastes and thermal pads.
