Phase Change Material Microcapsule / PCM Grain Composition ANDOR/AND/OR
Phase Change Materials (PCMs) are ideal products for thermal management solutions. This is because they store and release thermal energy during the process of melting & freezing (changing from one phase to another). When such a material freezes, it releases large amounts of energy in the form of latent heat of fusion, or energy of crystallisation. Conversely, when the material is melted, an equal amount of energy is absorbed from the immediate environment as it changes from solid to liquid.
This property of PCMs can be used in a number of ways, such as thermal energy storage whereby heat or coolness can be stored from one process or period in time, and used at a later date or different location. PCMs are also very useful in providing thermal barriers or insulation, for example in temperature controlled transport.
The simplest, cheapest, and most effective phase change material is water/ice. Unfortunately, the freezing temperature of water is fixed at 0°C (32°F), which makes it unsuitable for the majority of energy storage applications. Therefore a number of different materials have been identified and developed to offer products that freeze and melt like water/ice, but at temperatures from the cryogenic range to several hundred degrees centigrade.
Our PCM range can broadly be arranged into three categories: eutectics, salt hydrates, and organic materials
PCM is a material that stores and releases large amounts of energy when changing phases without affecting its own temperature, and thus it can control temperature, store heat and cooling. It does not contain poisonous substances like methanol, and does not decompose during the process. It is widely used in green building, textile, aviation and aerospace.
