    Abstract: Radiation curable phase change solutions (PCM) and said solutions as a thermoset thermal energy gels (a radiation cured polymeric network) has a hydrophobic PCM, a polybutadiene urethane acrylate oligomer soluble in the hydrophobic PCM and present as 7% wt/wt to 25% wt/wt of the gel, a photoinitiator soluble in the hydrophobic PCM and present as 0.01% wt/wt to 0.5% wt/wt of the gel, a mono-functional or di-functional crosslinker soluble in the hydrophobic PCM and present as 0% wt/wt to 10% wt/wt of the gel, and a hydrogenated styrenic block copolymer as a secondary resin as 0% to 20% wt/wt of the gel and optionally a tertiary resin as 0% to 5% wt/wt of the gel, wherein the tertiary resin is a hydrogenated styrenic block copolymer that is different than the secondary resin. The solution or gel is sealed in a container, e.g., a sachet, to form a cold pack.

    Abstract: Methods for producing a dimensionally stable phase change material (PCM), and dimensionally stable PCMs are disclosed. The methods include providing a porous base material, mixing a phase change material having a polar functional group with a substance that increases the polar attraction of the phase change material for the porous base material to form a mixture thereof; and, thereafter, mixing the mixture with the porous base material until a selected saturation of phase change material in the porous base material is reached. The methods may include filtering the porous base material after the selected saturation is reached to form a cake of dimensionally stable PCM and, thereafter, reducing the size of the dimensionally stable PCM to an average mean particle size of about 10 to about 50 μm, or more preferably 20 to 30 μm.

    Abstract: Solid gel beads formed from a gel product of a 5 carbon to 60 carbon alkane phase change material, 5 carbon to 60 carbon alkene phase change material, or a combination thereof and a styrene-based polymer are homogeneous, has an uneven exterior surface, and a major axis length in a range of 1000 μm to 100 mm. Methods for making the solid gel bead include providing water having a preselected temperature based on a linear relationship to the melting point of a phase change material composition, mixing the phase change material composition with the styrene-based polymer at or below the preselected temperature with stirring to form a pulp, and mixing the pulp into the water with turbulent mixing while maintaining the temperature of the mixture at the preselected temperature.
