Our PCMs provides specific temperatures for a variety of applications. The “phase” temperatures are the temperatures at which each product undergoes the phase change, or melting, from solid to liquid. These temperatures are 0°C (32°F), -7°C (19.4°F), -16°C (3.2°F), and -21°C (-5.8°F). The latent heat of each product allows all heat absorbed to be used in the melting process, or phase change, without any temperature change, providing a stable passive cooling system.
Each proprietary formula was specially designed to form a highly regular geometric structure when frozen, which is the basis of the large potential for heat energy storage. The specific ingredients of each formula pinpoint the temperature at which the phase change will occur. The non-hazardous solutions were also developed to cycle through the freeze/thaw phase change thousands of times without degradation of materials. Many substances can effectively act as a PCM, however, it requires extensive knowledge and research to develop a combination that allows them to maintain a constant exact temperature in the refrigerated or frozen range that is desired.
