70℃ Phase Change Material

【Product Introduction】

70℃ organic phase change materials (PCM) are ideal for thermal management solutions. This is because they store and release heat energy during melting and freezing (changing from one phase to another). When this material freezes, it releases a large amount of energy in the form of fusion latent heat or crystallization energy. In contrast, when a material melts, it absorbs equal amounts of energy from its surroundings as it changes from a solid to a liquid.

【 Performance index 】

1. Stable performance and shape: before and after the phase change are solid, no leakage problem.

2. High thermal conductivity efficiency: can release or store cold in time.

3.Accurate and balanced temperature control: phase change temperature 63-74℃, no supercooling phenomenon.

4. Recycling, efficient and environmental protection: small changes in thermal characteristics, reusable, safe and non-toxic, non-flammable and explosive.

5. Reasonable storage time: the storage time per unit mass is shorter than the traditional storage agent, which greatly improves the work efficiency.
