Compatibility of plastic with phase change materials (PCM ...

Even though paraffin interactions with plastics are known by industry, plastics are commonly proposed as container materials for encapsulating phase change materials (PCM) in many applications. In the literature, there are very few experimental studies of organic PCM migration in plastics and its effects on plastic properties.

Numerical analysis of effective thermal conductivity of ...

The effective thermal conductivity of mixed solid media is influenced by the weight (or volume) fraction of the doped material rather than by the size or dimension of each discrete phase. For illustration purposes, the effective conductivities of some phase change materials and plastics doped with metal powders are calculated.

Phase Change Materials | Textile World

Materials used in this work included paraffinic hydrocarbons, such as eicosane; and plastic crystals, such as 2,2-dimethyl-1,3-propanediol (DMP) and 2-hydroxymethyl-2-methyl-1,3-propanediol (DMP). When plastic crystals absorb thermal energy, the molecular structure is temporarily modified without changing the phase of the material.

Frequently asked questions about phase change materials

Phase change materials (PCM) are substances that absorb and release thermal energy during the process of melting and freezing. When a PCM freezes, it releases a large amount of energy in the form of latent heat at a relatively constant temperature. Conversely, when such material melts, it absorbs a large amount of heat from the environment.
