Product Specification

Universal Phase Change Microcapsules - Efficient Thermal Control Elements That Are Both Safe And Environmentally Friendly

How the product works:

1. When the phase change material in the capsule is completely in solid or liquid state, the temperature of the phase change material changes with the ambient temperature, and can not play the role of heat storage and temperature regulation.
2. Only when the phase transformation of the phase change material is in a solid-liquid mixed state, the temperature of the phase change material remains constant, and it converts heat from the environment to its own latent heat or releases its own latent heat to the environment, thereby maintaining the constant temperature of the environment.
3. Since the phase change material is always covered in the capsule, its shape remains basically unchanged when it expands or contracts.
4. Therefore, it is a phase change material with stable shape.

Highlights of the product:
1. Thermal stability

• It has good thermal stability in a certain temperature range and can keep its performance unchanged during multiple phase change cycles.

2. Temperature regulation

• It can automatically adjust its own phase state according to the change of ambient temperature, so as to absorb or release heat to achieve the effect of adjusting temperature.
• For example, in the field of construction, the application of phase change microcapsules in wall materials can make the indoor temperature more stable, reduce the frequency of use of air conditioning and heating, and achieve energy saving and emission reduction.

3. High security

• After microencapsulation, the phase change material is isolated from the external environment, reducing the risk of chemical reactions with other substances and improving safety during use.

4. Efficient energy storage

• Phase change microcapsules can absorb or release a large amount of heat during the phase change process, so as to achieve efficient heat energy storage and release, which helps to improve energy efficiency and reduce energy waste.

5. Customizability

• By selecting different phase change materials, shell materials and controlling parameters such as the size and wall thickness of microcapsules, the performance of phase change microcapsules can be customized to meet the needs of different application scenarios.

Product application scenarios:

-- Construction field
1. Energy-saving building materials

• Phase change microcapsules are added to building insulation materials (such as insulation panels, insulation mortar) or wall coatings.
• For example, in some experimental building projects, microcapsules with a phase change temperature of about 20-25°C are mixed with external wall insulation mortar.
• When the outdoor temperature rises during the day and the indoor temperature is close to 20-25°C, the phase change microcapsules absorb heat, delay the indoor temperature rise, and reduce the demand for air conditioning refrigeration.
• When the temperature drops at night, the microcapsules release heat, slow down the indoor temperature drop, reduce the frequency of heating use, and save about 20-30% of energy consumption.

2. Intelligent temperature control floor

• Phase change microcapsules are added to the floor material. For example, in the geothermal floor of some high-end residential or commercial places, when the sun exposure raises the floor temperature to the phase change temperature, the microcapsule absorbs heat to prevent the floor from overheating.
• When the indoor temperature drops, the microcapsules release heat and keep the floor at a certain temperature, making people feel more comfortable. This flooring helps to regulate the indoor microclimate and improve the comfort of the occupants.

-- Textile and garment industry
1. Smart tempering clothing

• Phase change microcapsules are added to clothing fibers. For example, the outdoor sportswear brand is used in its products such as ski wear and mountaineering wear.
• When the heat generated by human movement makes the temperature inside the garment reach a phase change temperature of about 37°C (close to human body temperature), the microcapsules absorb heat and make the wearer feel cool.
• When the human body is in a cold environment, the human body loses heat and the temperature drops, the microcapsule releases heat to keep the human body warm, improve the comfort and functionality of the clothing, and extend the comfortable activity time of the human body in extreme environments.

2. Functional home textiles

• The application of phase change microcapsules in mattresses, quilts, pillows and other home textile products.
• Taking the mattress as an example, when the person lies on the bed, the body heat makes the local temperature of the mattress reach the phase change temperature, the microcapsule absorbs heat, regulates the sleep environment temperature, reduces the number of turns caused by overheating or cold at night, and improves the sleep quality.

-- Health care
1. Medical cold compress/hot compress bag

• microcapsules with specific phase change temperature are made into medical bags. In the early stages of a sports injury, a microcapsule can absorb heat during the phase change process, providing a cold compress effect and reducing swelling and pain.
• In the rehabilitation phase, when the temperature reaches the phase change temperature, the heat is released to promote blood circulation and relieve muscle soreness.
• The pack is reusable and offers more precise temperature control than traditional ice packs and hot water packs.

2. Temperature control of medical equipment

• Phase change microcapsules are used in heat dissipation or insulation systems of some temperature-sensitive medical devices (such as blood analyzers, in vitro diagnostic devices, etc.).
• For example, some high-precision blood analyzer requires an operating temperature of about 37°C, phase change microcapsules are integrated into the temperature regulation module of the device, when the device temperature fluctuates slightly, the microcapsule absorbs or releases heat through phase change, so that the device remains within the precise operating temperature range, ensuring the accuracy of the test results.

Packaging and storage:
