A phase change material absorbs and releases thermal energy in order to maintain a regulated temperature.
Can phase change materials (PCM) be a valuable part of a thermal management solution? These ten facts can help you answer that question and determine what PCM might be right for you.
Phase change materials are unique as they provide completely passive thermal regulation – no power is needed to create this thermal regulation. In addition, PCMs can be used over and over again.
Due to the many advantages of organic PCMs over other the other two main PCM types, we will concentrate on organic PCMs. Microtek offers PCMs in three main forms:
Each of these forms has its own unique advantages and is best suited to certain applications.
This is the phase change material itself in its' simplest form. The material is a solid below its' melt point and a liquid above its' melt point.
The material can be melted above its' melt point and then poured into the suitable container (pouch, piping, plastic molded parts, etc.).

-30C, -10C, 6C, 18C, 24C, 28C, 32C, 37C, 43C and 58C.
Shipping and packaging, solar energy systems, radiant heat flooring, industrial/commercial apparel (work vests, etc.), thermal pouches
Encapsulation of the PCM creates a tiny, microscopic container for the PCM. This means that regardless of whether the PCM is in its' solid or liquid state, the PCM will be contained. The capsules have excellent chemical and thermal stability (250°C+).
The PCM microcapsules can be incorporated directly onto textiles, into latex or PU foams, into adhesives, into insulation, etc.
