Phase Change Material

Phase Change Materials (PCM) change their physical characteristics when absorbing and/ or releasing heat/energy. The materials vary in the ‘phase time’ and temperature range at which they melt or freeze. PCMs enable the principles of thermal mass to be applied to lightweight buildings and building elements without affecting the major benefits of the system approach.

Phase change material (PCMs) offer an alternate solution to energy storage. Using a similar heat transfer infrastructure, PCMs have the potential of providing a more efficient means of storage. PCMs can be either organic or inorganic materials. Advantages of organic PCMs include no corrosives, low or no undercooling, and chemical and thermal stability. Inorganics are advantageous with greater phase-change enthalpy. The greater phase-change enthalpy in inorganic PCMs make hydrate salts a strong candidate in the solar energy storage field.

Handling Measures
and Precautions

Proper human safety products such as splash goggles, lab coat, vapour respirator, NIOSH approved gloves and boots should be worn while handling and applying chemicals. Splashes on the skin should be washed off with water immediately. In case of splashing into the eyes, flush them with fresh water and obtain medical attention. Should not be injected.


Should be stored in original vented containers, away from heat, direct sunlight and combustibles. Store in a cool and dry place. Please refer label and SDS for details.
