Thermostatically Stable And Durable Phase Change Microcapsules - For A Variety Of Thermal Control Needs

Product Introduction:

• Phase change microcapsule is a new kind of phase change material. It is a kind of composite material with core-shell structure which is wrapped in tiny capsule by microcapsule technology.
• The diameter of phase change microcapsules is usually between a few microns to several hundred microns, and has a high specific surface area and thermal conductivity.

Product advantages:
1. 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.

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. Prevent leaks

• The phase-change material is encapsulated in microcapsules, which effectively prevents the leakage and erosion of the phase-change material during the molten phase change process, and improves the stability and service life of the material.

4. Good liquidity and dispersion

• Phase change microcapsules usually have good fluidity and dispersion, which makes them easy to mix with other materials and expand their application range.
• For example, when preparing temperature control textiles, phase change microcapsules can be evenly dispersed in textile fibers to give the textile temperature control function.

5. 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.

Product common application cases:
1. 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 (assumed to be 28°C), the microcapsule absorbs heat and prevents 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.

2. Thermal underwear

• Add phase change microcapsules to underwear.
• Some brands of thermal underwear products use this technology, in cold weather, microcapsules can continue to release heat, keep the underwear temperature in a comfortable range, to provide warmth for the human body.
• At the same time, due to its good temperature adjustment performance, it will not be as uncomfortable as traditional thermal underwear due to overheating, improving the wearing experience.

3. Medical cold/hot packs

• Microcapsules with specific phase change temperatures (such as 4-8°C for cold compress and 40-45°C for hot compress) 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.

Packaging and storage:
1. Packing method

• 25 kg/bag

2. Storage method

• Dry, cool and ventilated place without sharp objects.
