PCMs, or phase change materials, act as thermal regulators depending on the thermal conditions of the environment. There are PCMs of inorganic and organic nature, but the latter are based on polymers which are more stable and capable of storing and releasing greater amounts of energy. This behavior occurs with the reversible phase change material (PCMs), such that heat absorbed or released when the material passes from solid to liquid and vice versa. When the temperature rises and the temperature of phase change reaches the PCM melts absorbing heat from the environment, while when the temperature drops below the temperature of phase change, solidifies releasing heat. Most of PCMs on the market are presented encapsulated. Regardless of (liquid or solid) state of the PCM, the nanocapsule containing it remains in solid state providing protection and preventing release.
This type of product has been developed for a variety of applications, such as cooling systems, energy sustainable buildings, aerospace coatings, paints interior, smart textiles.
Laurentia technologies has developed a line of products based on PCMs with thermoregulatory capacity and improving energy efficiency and product application in different sectors. This same technology can be adapted to the design of different applications by appropriately selecting the temperature range in which to exercise regulatory properties.
The main difference Laurentia technology over other products is the siliceous capsule thanks to its higher thermal conductivity improves the storage capacity and energy release. In addition it is more resistant to potential problems of breakage during handling or processing of the material capsules.
