Encapsulated phase change material

A manufacturing technology to produce very small encapsulated phase-change materials has been developed (47). These encapsulated phase-change materials were appHed in a convective heat-transfer test section, and a 50—100% higher heat-transfer coefficient was reported.

Gateway Technologies has reported the application of heneicosane, eicosane, nonadecane, octadecane, and heptadecane as phase change materials for insulative fabrics. This material can be 425% as warm as a high bulk wadding. Schoeller Textil AG Switzerland has also explored the application of micro-encapsulated phase change materials like waxes, which offer interactive insulation for skiwear, snowboarding and ski boats. They store surplus heat and the wax liquefies when temperatures drop, the microcapsules release the stored heat.
