Gist”:   “Polyurethane phase change gels” prepared from polyurethane gels and conventional PCMs are incorporated into polyurethane or latex flexible foams to improve thermal comfort.

Why it is interesting: This application is closely related to the application discussed in the previous post but instead of a plasticized styrenic triblock copolymer, now a polyurethane gel is used. The PU gel is produced from conventional raw materials at low NCO-index (about 60%) together with plasticizers.
