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.
