In the growing number of mattresses in circulation, mattress covers and other bedding products are multiplying which allow or try to do so to control body temperature and keep you comfortable and fresh all night long. Today we will talk about PCM to always have a fresh memory mattress.

The magic of science behind the fresh mattress:
The technology behind these thermoregulation products is phase change materials (PCM). Phase Changing Materials have become increasingly popular due to their properties that enable energy optimization.
Just as their name suggests, phase-change materials are matter that change from one phase such as liquid, vapor, or solid to another phase depending on their temperature. It can, therefore, be said that all materials, starting from water, are PCM. However, the PCMs used to have a fresh mattress are very sensitive to temperature changes; even the smallest ones.
PCMs in nature:
A natural PCM is, as anticipated, water. When the temperature drops to freezing (0 ° Celsius), the water solidifies and turns in the ice. When we put ice in a beverage at more than 0 ° C, it melts in an effort to stabilize the temperature and keeping the drink cold.
This is because between two materials in contact there is a heat exchange, which lasts until the thermal equilibrium is reached. PCMs are well-known in many types of products because they can soak up or release huge energy amounts and maintain a constant temperature.
Researchers and engineers study the applicability of PCMs in a wide variety of objects, from refrigerators to energy-efficient building materials; to reach polyurethane fabrics and foams, necessary so that we can always have a fresh mattress.
How does PCM maintain a fresh memory mattress?
This temperature regulation technology that uses PCM physics can be seen in various brands that sell sleep products.
In practice, phase change materials can be found enclosed in fiber microcapsules, which are transformed into yarn and then used to make foams, slabs and other items to have a fresh memory foam mattress. They can also be used with popular fabrics such as acrylic, although the performance is optimized in the synthetic polyester fibers.
