Specialized Phase Change Material Customized For The Pharmaceutical Refrigerated Packaging Within The 25°C Cold Chain Framework

Features:

1. Energy storage characteristics

• When a phase change material changes from one phase state to another, it absorbs or releases a large amount of heat. In the cold chain, this property can be used to maintain a stable temperature in the environment surrounding the cargo.
• For example, when the ambient temperature rises, the phase change material absorbs heat and changes from a solid state to a liquid state, thereby slowing down the rise in ambient temperature; When the ambient temperature decreases, the PCM releases heat and may change from a liquid state to a solid state, preventing the ambient temperature from getting too low.
• Its energy storage capacity is usually expressed in enthalpy, and the higher the enthalpy, the more heat is stored or released. Different PCMs have different enthalpy values, and the right material needs to be selected according to the specific cold chain needs.

2. Appropriate phase change temperature

• For 25°C cold chain PCMs, it is critical that the phase change temperature is around 25°C. This temperature range is suitable for many goods that need to be refrigerated but cannot be too cold, such as certain medicines, food, etc.
• For example, the storage temperature of some vaccines is required to be between 2°C and 8°C, and the use of 25°C phase change materials can absorb heat through the phase change process when the outside temperature rises to a certain level, and maintain the refrigeration environment within the appropriate temperature range.

3. Stability

• In terms of chemical stability, PCMs need to be able to maintain their chemical properties over multiple phase change cycles in cold chain applications. It should not decompose or chemically react with packaging materials due to repeated melting and solidification, otherwise the quality and safety of the goods may be affected.
• Thermal stability is also important to be able to maintain its phase change characteristics over long periods of thermal cycling. For example, after several heating and cooling cycles, the phase transition can still occur accurately at around 25°C, and the enthalpy of the phase change will not drop significantly.

Fields of application:

1. Pharmaceutical cold chain

• Temperature control is crucial during the transportation and storage of pharmaceutical products. Many pharmaceutical products, such as biologics, vaccines, etc., have very strict temperature requirements. 25°C cold chain special phase change material can be used in the refrigerated packaging of drugs, when the outside temperature fluctuates, the phase change material through the phase change to maintain the temperature around the drug in the appropriate range.
• For example, during the transportation of vaccines, a refrigerated package containing PCM is placed in a transport box with the vaccine, and even if there is a brief temperature increase during transportation, the PCM can absorb the heat and ensure the quality and effectiveness of the vaccine.

2. Food cold chain

• Some fresh foods, processed foods, etc., also need to be stored and transported at specific temperatures. For example, some fruits and vegetables can be kept fresh at temperatures close to 25°C, and the use of 25°C PCM can maintain the freshness and quality of food during the cold chain logistics process.
• For example, when transporting fruits such as strawberries, an ice pack made of PCM is placed in a box, and when the outside temperature rises, the PCM in the ice pack absorbs the heat and melts, reducing the temperature inside the box and prolonging the shelf life of the strawberry.

3. Transportation of electronic equipment

• Some temperature-sensitive electronic devices also need to be kept within a certain temperature range during transportation. While the optimal operating temperature for electronic devices may not be 25°C, 25°C cold chain-specific phase change materials can act as a buffer to some extent.
• For example, when transporting precision electronic instruments, the phase change material is packaged around the instrument, and when the temperature of the transportation environment changes greatly, the phase change material can absorb or release heat, reduce the impact of temperature fluctuations on electronic equipment, and prevent equipment from being damaged due to too high or too low temperature.
