Principle of Phase Change Insulation Material

- When heated to the melting temperature, a phase change from solid to liquid occurs, and during the melting process, the phase change material absorbs and stores a large amount of latent heat.

- When the phase change material is cooled, the stored heat is emitted to the environment within a certain temperature range, and the reverse phase change from liquid to solid is carried out.

- The energy stored or released during these two phase change processes is called the latent heat of phase change. When the physical state changes, the temperature of the material itself remains almost constant until the phase change is complete, forming a wide temperature plateau, although the temperature remains constant, but the latent heat absorbed or released is quite large.
