In such a type of PCM, paraffin, as the solid–liquid phase change material, is dispersed into the polymer network of HDPE. The HDPE compound in the composite PCM is considered as a supporting material to prevent leakage of the melted paraffin from the composite at a temperature between the melting temperatures of paraffin and HDPE.
