-21°C Phase Change Materials: The Optimal Solution For Low-Temperature Refrigeration And High-Efficiency Energy Storage

Product Introduction:

• -21℃ phase change material is a kind of functional material that can undergo phase transition at about -21℃, accompanied by significant heat absorption or release.
• It is mainly composed of inorganic salt hydrate, etc., by adding various functional additives, through the process of compounding.
• This material plays an important role in cold chain logistics, medical refrigeration, scientific research and other fields that have strict requirements for low temperature environment, and can effectively maintain the relative stability of specific environmental temperatures, ensuring that the quality and performance of goods are not affected by temperature changes.

Product quality features:
1. Precise phase change temperature

• Its phase change temperature is about -21°C, which can accurately absorb or release a lot of heat near the specific temperature, so that the ambient temperature remains relatively stable, so as to meet the requirements of application scenarios with high temperature control accuracy.

2. High storage capacity

• With high cold storage density, it can absorb and store a large amount of cold during the phase transition process, so as to release it when needed, providing continuous and stable cold source support for low temperature environment.

3. Good thermal stability

• After many phase change cycles, the performance of the material can still remain stable, not easy to decompose, deteriorate or performance decay and other problems, can be repeatedly stored and released cold capacity, long service life, can be reliably applied to long-term low temperature environmental control occasions.

4. Simple material packaging

• The packaging of the material is relatively simple, and there is no risk of leakage after packaging, which is easy to manufacture and use operation, and can ensure the safety and reliability during use. It can be filled with solid-liquid or solid-solid phase change materials, and can also be customized packaging according to different application requirements.

5. Performance is adjustable

• Its phase change temperature, latent heat, thermal conductivity and other properties can be adjusted according to the specific application requirements, by adjusting the formula and process parameters of the material, can achieve different combinations of properties, in order to better adapt to the diverse use of the environment and conditions.

Product application case:
1. Cold chain logistics

• The use of -21℃ phase change materials in the thermal insulation freezer can ensure that the temperature in the box is stable at about -21℃, providing a long-term low temperature preservation environment for temperature-sensitive items such as fresh food and biological products, and extending their shelf life and shelf life.

2. Medical field

• It is used for outdoor storage and constant temperature transportation of insulin and other drugs, to ensure the activity and stability of drugs during transportation and storage, and to ensure that its efficacy is not affected by temperature changes.
• In addition, in the preservation of some medical testing reagents and biological samples, -21℃ phase change materials can also play an important role in maintaining the low temperature state of the samples, providing guarantee for accurate detection and research.

3. Scientific experiments

• In some scientific experiments requiring a low temperature environment, such as experiments in chemistry, physics, biology and other fields, -21℃ phase change materials can be used as a stable low temperature source, providing accurate temperature control for the experiment, helping to ensure the accuracy and reliability of the experimental results.

4. Cold storage air conditioning

• In the night low electricity price period, the use of -21 ℃ phase change materials to store cold capacity, the daytime peak electricity release cold capacity, to achieve "peak shift valley filling", reduce the operating cost of the air conditioning system, while reducing the frequent start-up of the compressor, improve the stability of the system and energy utilization efficiency.

5. Cool pad

• After being made into a cool pad, in the summer high temperature, -21℃ phase change material can absorb the heat emitted by the human body, provide a cool and comfortable body feeling for the human body, and effectively alleviate the discomfort brought by hot weather.

Packaging and storage:
1. Packing method

• 53 kilograms per barrel.
• 1,000 kilograms per ton of barrel.
• In addition to the above two options, support customized according to customer needs.

2. Storage method

• Dry, cool and ventilated place without sharp objects.
