Phase-change materials
Materials that store and release cooling through liquid-solid phase change, for cold-chain transport, refrigeration, ice-and-snow facilities and thermal-storage systems.
Formulated phase-change energy storage materials
| Model | Freezing point (°C) | Melting point (°C) | Latent heat (kJ/kg) | Density at 20°C (g/cm³) | Thermal conductivity at 20°C (W/m·K) | Specific heat at 20°C (cal/g·°C) |
|---|---|---|---|---|---|---|

LM-XL-5 is deliberately not tabulated: its printed freezing point (−3.5°C) is warmer than its printed melting point (−5.5°C), which no other grade shows. Confirm the definition, test method and whether this is a transcription error before any figure is published.
Catalogue reference values, not a final specification. Select the exact model and concentration with our technical team. Request the current technical data sheet and safety data sheet before use.

FROM FORMULATION TO APPLICATION
LM-XL materials store and release cooling through phase change. The original product references describe applications in refrigerated transport, pharmaceutical distribution and fruit-and-vegetable preservation.
Select against the required product-temperature band and duration. Freezing and melting temperatures may differ and are not the same as a circulating-fluid operating range.
Confirm containment, charging conditions and thermal cycling for the selected grade. Product-storage applications do not imply direct food or pharmaceutical contact approval.

Phase-change materials are specified by a transition temperature, not a working setpoint. See how the catalogue presents its grades and what to verify first.
