Phase Change Microcapsules With Precise Temperature Control And Stable Performance - Essential Materials For Efficient Thermal Management

Product Overview:

• Phase change microcapsule is a kind of micro and nano capsule which is composed of specific phase change material by special process. When the external temperature changes, the core material in the microcapsule will undergo phase change, absorb or release a large amount of latent heat, so as to achieve the effect of self-regulating temperature.
• The product has the characteristics of high enthalpy value, high energy storage, high pressure resistance, low undercooling, etc. It is used in intelligent temperature-sensing fabrics, electronic equipment cooling and heat storage, air conditioning cold storage. Industrial waste heat recovery and other fields.

Product advantages:
1. Warm in winter and cool in summer

• To realize the cooling of textile heat, cold and warm, dynamic monitoring.

2. Thermal management material Nova

• Effectively deal with the influence of transient heat load on electronic equipment.

3. Improve energy storage

• Increase system enthalpy value, save energy and resources.

4. Wide range of application

• For the construction field, electronic equipment field, textile field, medical field, aviation field and other fields, the use of phase change microcapsules has been widely added.

5. Safe for consumers

• Non-toxic and harmless, safe to the problem, in line with environmental requirements.

Common application cases of the product:
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. 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.

3. Computer CPU heat dissipation

• The phase change microcapsule is applied to the heat sink paste or heat sink coating of computer CPU heat sink.
• When the temperature of the CPU rises to the phase change temperature (such as 60-70 ° C) when the CPU is working at a high load, the microcapsule absorbs and stores heat to prevent the CPU from overheating, thereby maintaining the stability of the computer performance and avoiding problems such as crash and frequency reduction caused by overheating.
• Experiments show that the peak temperature of the CPU at high load can be reduced by 10-15 ℃ after the use of thermal materials containing phase change microcapsules.

Packaging and storage:
1. Packing method

• 25 kg/bag

2. Storage method

• Dry, cool and ventilated place without sharp objects.
