  4. Low Evaporation Rate

Low Evaporation Rate

CrodaTherm™ bio based phase change materials have exceptionally low volatility. This means that even at high temperatures, they resist evaporation. This means for manufacturing processes that require elevated temperatures for incorporating PCMs into finished goods, less phase change material will be lost.

Phase Change Materials

We manufacture bio-based PCMs that utilise our expertise in organic, plant based chemistries; they are not paraffinics or salt hydrates. CrodaTherm PCMs melt to absorb heat and solidify to release heat at defined, specific temperatures.
