Biobased phase change material and expanded polystyrene

Expanded polystyrene, commonly used in coffee cups, coolers and packaging, will dissolve if it comes in contact with most vegetable oils, including biobased phase change material. The phenomenon is proving effective as a “green” solution to reducing EPS waste. But it demonstrates that care must be taken in both the containment and shipment of organic phase change material.

Thermal Cycling 101

A thermal cycling study is designed to determine the cycling stability of a phase change material. During the study, a PCM goes through 10,000 or more cycles as quickly as possible to see if any thermal or chemical degradation is observed. The results help determine the useful lifetime of a PCM and its suitability for various applications.
