1. phase change wax (solid-liquid phase change material) is the use of solid and liquid between the phase change process (melting and condensation) at almost constant temperature to absorb and release a large amount of thermal energy, play a role in energy storage energy saving, temperature regulation, protection of electronic devices and increase the thermal inertness of the object. GSC® FPC series products are an organic normal alkane solid-liquid phase change energy storage material (PCM), which belongs to the linearity and narrow carbon number distribution of linearity and linear alkanes, which has good reversibility of solid-liquid phase change and can be recycled many times;at the same time, solid molding is good, and there is no supercooling and phase separation in the phase transition process. 2. The production of GSC® FPC series products combines some or all of the following process technologies: a. Special liquid-liquid separation (molecular distillation) technology - unlike traditional atmospheric vacuum distillation, which relies on the principle of boiling point difference separation, but relies on the difference in the average free path of molecular motion of different substances to achieve separation; b. New melt crystallization purification technology - using the difference in freezing point between the components or key components of the separated substance, by adjusting the energy transmission control, one of the components crystallizes and precipitates, the molten liquid becomes a suspension, and then the solid-liquid separation is carried out to obtain a pure solid crystallization or re-melting liquid product; c. Blending modification technology - improve the thermal conductivity of phase change materials, according to user needs, through the screening and addition of thermal conductive materials, to meet the special needs of users in terms of product heat transfer efficiency. 3. GSC® FPC series products are suitable for preparing micro droplets into microcapsules or using hollow porous solid carriers, adsorbing the phase change wax in porous particles by physical adsorption method, and then encapsulating to prepare a composite phase change material. 4. Grandstar can provide you with a full range of phase change wax products from 44 °C to 125 °C, some of which have a latent heat of phase change of more than 230kJ/kg, which can meet the needs of electronics, military, aerospace and other applications with higher product purity requirements. If you can't see the temperature product you need from here for your application, don't hesitate to contact us, Grandstar can produce almost every grade of phase change wax in the temperature range described above.
