Product Details
-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.
