Phase Change Material
What are phase change materials?
Phase change materials are capable of storing and releasing energy. The heat that gets absorbed/ released when the Phase Change Material changes from solid to liquid state and vice versa. Therefore, the Phase Change Materials are categorized as latent heat storage (LHS) units.
Phase Change for Positive Temperatures
Phase Change Materials/ Media are chemical formulations that can alter their state of matter (viz., Freeze & Thaw cycle) without changing temperature. There are various types of PCM products for different phase change temperature and latent heat requirements. The range covers all products having phase change point from 0°C/ 32F to 115°C/239F. There are several factors that are considered while selecting a phase change material, some of them are:
- Having high heat of fusion
- Having high thermal conductivity
- Having high specific heat and density
- Having long term reliability during repeated cycling
- Having dependable freezing behavior
Key Features and Benefits
- Phase change temperature in desired range with sharp melting/freezing point
- High latent heat of fusion (solid to liquid)
- Non‐toxic & non‐carcinogenic
- Commercially available at low cost
- Does not react with and/or act as a solvent for packaging materials
- Landfill disposable and/or waterway disposable
- Biodegradable nature
- Low/non‐flammable (high flash point, low vapor pressure)
- Non‐corrosive
Phase Change at Sub Zero
This range of PCMs incorporates solutions of various blends that condense below 0°C. PCM Products provide a wide range of solutions, freezing and melting at temperatures between -2°C to -62°C. The solutions are formulated in order to minimize super cooling, and where necessary may contain other additives such as corrosion inhibitors and microbiocides. This ensures long term reproducible freeze and melt cycles throughout the PCMs' usage. PMC Eutectic Salts and Solutions are ideal products designed for thermal energy storage system. PMC functions in storage and release of thermal energy during melting and freezing process i.e. when they are changing from one phase to the other. When PMC freezes it releases large amount of energy in the form of latent heat of fusion or energy crystallization.
