Abstract
A fusible, phase-change powder composition includes a plurality of powder particles comprising a polymer composition, an unencapsulated phase-change material, and optionally, an additive composition; wherein the powder composition is fusible at a temperature of 25 to 105° C., or 28 to 60° C., or 45 to 85° C., or 60 to 80° C., or 80 to 100° C.
Claims20
A fusible, phase-change powder composition, comprising:
- a plurality of powder particles comprising
- 5 to 20 weight percent of a polymer composition comprising a styrene-ethylene/propylene-styrene block copolymer, a styrene-butadiene block copolymer, or a styrene-ethylene/butylene-styrene block copolymer,
- 80 to 97 weight percent of an unencapsulated phase-change material comprising a paraffin having a melting temperature of 35 to 60° C., wherein weight percent is based on the total weight of the phase-change powder composition, and
- optionally, an additive composition;
- wherein the powder composition is fusible at a temperature of 25 to 105° C.
