Paraffin microcapsule phase change materials are widely used and have great market potential

In recent years, phase change materials have developed rapidly, among which paraffin phase change insulation materials are widely used. This is due to the characteristics of paraffin materials such as wide phase change temperature, medium heat storage density, high phase change enthalpy, good chemical stability, and non-corrosiveness. However, paraffin solid-liquid phase change materials have large volume changes, are flammable, easily oxidized, and have poor thermal conductivity, so there are certain limitations in their use. Phase change microcapsules are functional materials that put phase change materials into microcapsules and use the phase change latent heat of the phase change materials during the phase change process to store and release heat. Using microcapsule technology, paraffin is used as the phase change capsule core. During the phase change process, the paraffin undergoes a solid-liquid phase transition. This is the paraffin microcapsule phase change material. The wall materials of paraffin microcapsule phase change materials mostly use organic materials such as natural polymers and synthetic polymers.

“2022-2026 Paraffin Microcapsule Phase Change Materials Industry In-depth Market Research and Investment Strategy Suggestions Report compiled and released by the Industrial Research Center It shows that paraffin microcapsule phase change materials can well solve the problem of shape and volume changes when solid-liquid phase change materials change into liquid, and expand the use of paraffin phase change materials. At present, paraffin microcapsule phase change materials can be used in construction, textile and clothing and other fields.

Construction is the most important application field of paraffin microcapsule phase change materials. This is because modern building materials are mainly reinforced concrete. This type of material has high mechanical strength, but low specific heat. The indoor temperature fluctuates greatly due to the influence of the external environment. For The demand for cooling and heating is huge. In the context of the green development of the construction industry, energy conservation and emission reduction in the construction industry have become a major focus of industry development, and seeking a balance between comfort and energy consumption has become a major focus of industry development. Microcapsule phase change materials used in the construction field can increase the specific heat of building materials and thereby improve indoor comfort. Currently, paraffin phase change microcapsules are used abroad as building insulation materials to achieve building energy conservation. With the development of global building energy-saving trends, it is expected to drive the demand for paraffin microencapsulated phase change materials.

Paraffin microcapsule phase change materials can also be used in the textile industry to produce temperature-regulating fabrics, and then produce temperature-regulating fabrics, which can sense temperature and respond to changes in the environment and human body temperature, absorb or release heat, and achieve a thermal insulation effect. At present, selvage striped textiles are mainly used in the aerospace field. With the continuous development of technology and the reduction of costs, the promotion in the civilian field is also expected to gradually advance. With the continuous development of technology, the growth of temperature-regulating fabric production capacity, and the improvement of downstream awareness, the temperature-regulating fabric market is expected to grow.

In addition, paraffin microcapsule phase change materials can also be used in infrared stealth, heat exchange and other fields. It is estimated that in 2025, the global paraffin microcapsule phase change material market will exceed 1.5 billion yuan. Paraffin microcapsule phase change material companies mainly include BASF, Germany’s Rubitherm, etc.
