Compositions de substance à changement de phase (pcm) pour regulations thermiques

The present invention relates to a Phase Change Material (PCM) composition comprising a) from 20 to 80 wt% of a PCM; and b) from 20 to 80 wt% of one or more polymers chosen from the group consisting of b1) Very Low Density Polyethylene (VLDPE) having a density equal or lower than 0.910 g/cm3 measured according to ASTM 792; b2) Ethylene Propylene Rubber (EPR) having a density equal or lower than 0.900 g/cm3 measured according to ASTM 792; b3) Styrene Ethylene Butylene Styrene (SEBS) copolymers; and b4) Styrene Butadiene Styrene (SBS) copolymers wherein the PCM composition is obtainable by soaking the different components all together at temperatures which are slightly above the melting point of the PCM but below the melting point of the one or more polymers. The PCM composition of the present invention can be used in applications where thermal management is needed, like for example in building, automotive, packaging, garments and footwear.
