A phase change material absorbs and releases thermal energy in order to maintain a regulated temperature.
Microtek currently concentrates on organic PCMs and offers raw PCM Blends as well as three forms of microencapsulated PCM: slurry, wet cake and dry powder.
These forms have their own unique advantages and are 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.).
Unencapsulated parrafin PCM Blend.
-30C, -10C, 6C, 18C, 24C, 28C, 32C, 37C, 43C and 58C.
Microencapsulation of the PCM creates a tiny, microscopic container for the PCM. The PCM is contained in this capsule during its solid and liquid state.
The PCM microcapsules can be incorporated directly onto textiles, into latex or PU foams, into adhesives, into insulation, etc.
Slurry: ~35- 45% solids aqueous suspension
Wet cake: ~70% solids, 30% water
Dry powder: >97% solids
-10C, 6C, 18C, 24C, 28C, 32C, 37C, 43C and 57C.
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.
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.
We have extensive knowledge in the application of phase change materials.

The Microtek Development Kit assists you in identifying the best solution for your specific requirement. By selecting up to three specific PCM samples: type, form and temperature, the Development Kit provides the resources to personally test and experiment with the PCM materials to determine the best performance for your application.
