When the PCM changes from a solid to a liquid, energy is absorbed but the temperature remains the same, and so the material can be used as a ‘temperature buffer’. Such a material can be added to other materials such as plaster or rubber to make them responsive to environmental change.

The material is supplied as a microencapsulated powder that can be used as an additive. This has a phase–change temperature of 23°C. If you place a finger on the powder, phase change commences and draws out heat so that it feels very cold. The material can be used to show the phase change principle and can be applied in design and technology – e.g., the powder could be added to a matrix such as plaster or placed in a sealed container to create a ‘smart’ liner for keeping drinks cans cool.
