Phase change material (PCM) is a kind of special material that can change its physical state (e.g. transition between solid and liquid, gas, etc.) within a specific temperature range and absorb or release a large amount of latent heat during the phase change process. With excellent energy storage density and stable temperature control performance, phase change materials are widely used in many fields such as building energy saving, solar energy utiliza-tion, heat dissipation of electronic equipment and cold chain logistics.

Guangzhou Cesin Cold Chain Technology Co., Ltd, with its own chemical laboratory and a specialized R&D team, has been deeply engaged in the field of phase change materials, integrating R&D, production, and testing services.
