A polymer composition comprising: (a) from 50% by volume to 99% by volume, preferably from 70% by volume to 95% by volume, of at least one homopolymer or copolymer of ethylene; (b) from 1% by volume to 50% by volume, preferably from 5% by volume to 30% by volume, of at least two fillers having different thermal conductivity; (c) from 100 ppm to 4000 ppm, preferably from 200 ppm to 3500 ppm of at least one fluoropolymer; the sum of (a)+(b) being 100. Said polymer composition can be used as a phase change material (PCM), in particular for thermal energy storage (TES), more in particular for the storage of solar energy.
