ThermoBall is a microcapsule product that contains phase change material, PCM* . The functional product absorbs heat as surrounding temperature goes up, and slow releases it as the temperature goes down.

When the product is applied to clothes, the thermal storage microcapsule makes it phase changed by the temperature change in the external environment and skin to cause heat absorption or heat release.

Such action is employed to give cooling and warming effects on the human body and thereby improve a wearer’s thermal freshness.

*What is PCM? PCM stands for Phase Change Material. It means a material whose phase change
