Phase Change Material

Keep Any Temperature
at your service



PCM Phase Change Material can store thermal energy in the form of latent heat for cooling or heating functions in a later stage. Energy storage is as important as new clean energy in terms of environmental protection.


From -100℃ to 1,100℃, different type of PCM has different phase change temperature so that its energy-storing phase change process can be sustained by specific natural hot/cold source without extra energy.


PCM built into panels or sheets can be used to keep stuff at specific temperature required for temperature-controlled applications: advancing chiller system efficiency, facilitating a cold chain or storing solar energy.

What is PCM?

Boca Phase Change Materials
BocaPCM Panel

Phase Change Material (PCM) is an organic compound capable of absorbing and releasing thermal energy during the process of melting and freezing. It can magically enable the temporary storage of precious heat and coolness for later use. This not only helps save a lot of energy but also fulfill the special and harsh needs for some temperature-controlled applications, even with extreme heat or ultra-cold requirements.

In practical use, Boca usually fills PCM solution into a panel. For example, the 8℃ PCM panels are widely used for HVAC chiller plant projects. We also offer PCM at different phase change temperature for different hot or cold functions.

  Boca International Limited (BIL) holds the patents and the trademark of BocaPCM.
