Global Phase Change Heat Storage Material Market – View in Detailed Research Report

Phase Change Heat Storage Materials (PCMs) are advanced substances that absorb, store, and release large amounts of thermal energy as they transition between physical states, typically from solid to liquid and back. This process, known as latent heat storage, allows them to manage temperature far more efficiently than traditional sensible heat storage materials. The primary categories include organic PCMs like paraffins and fatty acids, inorganic PCMs such as salt hydrates, and bio‑based PCMs derived from renewable sources.
