Abstract
The invention provides shape-stable products for storing and releasing thermal energy, based on thermoplastic polymer compositions containing organic phase change materials (PCM) incorporated into a polymer matrix, the products withstanding multiple melting-crystallization cycles of the PCM while maintaining their shape, dimensions, and the thermal energy storage capacity.
