-4°C Thermal Management PCM Prevents It From Melting Or Excessive Temperature Fluctuations During Transportation

Composition & Structure:

• It usually consists of a suitable phase change material and encapsulation material. Phase change substances may include some specific organic compounds (such as some fatty acids, alcohols, etc.) or inorganic salt hydrates, etc., which can undergo phase transformation at about -4°C. The encapsulation material is generally a polymer material, which encapsulates the phase change substance, and the common structure is the microcapsule structure.
• In the microcapsulated structure, the polymer shell encapsulates the core material of the phase change, which can prevent the leakage of the phase change material on the one hand, and facilitate its combination with other materials or systems on the other hand.

Performance Characteristics:

1. Thermal storage and release characteristics

• When the ambient temperature approaches or reaches -4°C, the PCM begins to undergo a phase transition. If the temperature drops from above -4°C to -4°C, the PCM will change from one state (e.g., liquid) to another (e.g., solid), releasing a large amount of latent heat, thereby slowing down the rate of decline in the ambient temperature and maintaining a relatively stable temperature environment.
• Conversely, when the temperature rises from below -4°C, the PCM changes from a solid to a liquid state, absorbing heat and preventing the temperature from rising too quickly. For example, in some low-temperature preservation applications, the -4°C thermal management PCM can adjust the temperature of the storage environment through a phase change to ensure the quality of the stored items.

2. Temperature stability

• During phase transitions around -4°C, PCM is able to maintain a relatively constant temperature over a relatively narrow temperature range. This is important for applications where temperature stability is required.
• For example, in the cryopreservation of some biological samples, the temperature needs to be precisely controlled at about -4°C, and PCM can maintain the temperature stability of the sample storage environment through phase change to ensure the viability and quality of the sample.

3. Reusability

• PCM is able to withstand multiple phase change cycles without significant degradation in performance. This allows it to be repeatedly operated for thermal storage and release during different temperature change cycles with good durability.
• For example, in some seasonal cryogenic storage facilities, such as cold storage for agricultural products in winter, the -4°C thermal management PCM can continuously adapt to temperature changes throughout the storage cycle and continue to perform thermal management functions.

4. Adaptability and adjustability

• By selecting different phase change material compositions, proportions, and changing the packaging method, the PCM can be adjusted to meet the specific requirements of -4°C thermal management in different application scenarios.
• For example, in different food refrigerated transportation processes, according to the characteristics and requirements of the transported goods, suitable -4°C thermal management PCM can be customized to ensure the quality and safety of the goods.

Fields of application:

1. Food refrigeration and transportation

• In the refrigerated transportation of fresh food, frozen food, etc., the -4°C thermal management PCM can be used to maintain a low temperature environment during transportation.
• When the outside temperature fluctuates, the PCM absorbs or releases heat through a phase change, ensuring that the goods are always in the appropriate temperature range of around -4°C, preventing food from spoiling or deteriorating quality.
• For example, when transporting frozen desserts such as ice cream, PCM prevents them from melting or fluctuating temperatures too much during transport.

2. Medical field

• In the storage and transportation of some pharmaceuticals and biological products, -4°C thermal management PCM can ensure that it can be stored in a suitable low temperature environment.
• For example, some vaccines need to be stored and transported at a temperature of around -4°C, and PCM can maintain a stable temperature through phase change to ensure the effectiveness and safety of the vaccine.
• At the same time, in the storage of some medical samples, such as blood samples, PCM can also help maintain the required low temperature environment.

3. Low temperature protection of electronic equipment

• When some electronic components or devices operate in a low temperature environment, they need to be kept within a certain temperature range to ensure normal operation and stable performance. -4°C thermal management PCMs can be applied to heat dissipation or insulation systems for these electronic devices.
• For example, in some electronic devices used outdoors, when the ambient temperature is too low to -4°C, PCM can release heat and prevent the performance of electronic components from being compromised due to low temperatures.

4. Low temperature protection of buildings and facilities

• In some buildings or facilities in cold regions, such as small cold storages, cryogenic laboratories, etc., -4°C thermal management PCM can be used as part of the insulation material. It can reduce energy consumption by adjusting the temperature indoors or inside the facility through phase change when the outside temperature changes.
• For example, adding PCM to the wall of a small cold storage allows the PCM to absorb heat when the outside temperature rises, preventing the internal temperature of the cold storage from rising too fast and reducing the operating load of the refrigeration equipment.
