PCMs-Phase Change Materials are designed for a wide range of temperatures. PCMs-Phase Change Materials are designed for a wide range of temperatures. Phase change materials are substances that absorb and release heat energy when they change phase (known as latent heat). Different materials will melt and solidify at different temperatures and are able to absorb different amounts of heat energy.

Phase change materials are useful because they melt and solidify at specific, defined temperatures, making them suitable to control the temperature in the range of diverse applications. Materials that melt to absorb heat are much more efficient at absorbing heat energy compared to sensible heat energy materials. This means that it takes a much smaller amount of a material to store heat energy phase change material than using a material that does not change phase.
