Title (EN) POLYMER COMPOSITION AND ITS USE AS A PHASE CHANGE MATERIAL
(FR) COMPOSITION POLYMÈRE ET SON UTILISATION EN TANT QUE MATÉRIAU À CHANGEMENT DE PHASE
Abstract: front page image
(EN)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.
(FR)L'invention concerne une composition polymère comprenant : (A) de 50 % en volume à 99 % en volume, de préférence de 70 % en volume à 95 % en volume, d'au moins un homopolymère ou copolymère d'éthylène ; (b) de 1 % en volume à 50 % en volume, de préférence de 5 % en volume à 30 % en volume, d'au moins deux charges présentant une conductivité thermique différente ; (c) de 100 ppm à 4000 ppm, de préférence de 200 ppm à 3500 ppm, d'au moins un fluoropolymère ; la somme de (a) + (b) valant 100. Ladite composition polymère peut être utilisée comme matériau à changement de phase (MCP), en particulier pour le stockage d'énergie thermique (SET), plus particulièrement pour le stockage d'énergie solaire.
