This poster aims to develop an Expanded Polymer that satisfies both the advantages of thermoplastic and the light weight through the application of a foam system using supercritical fluid. TPU is a thermoplastic elastomer with the most excellent tensile strength and wear resistance among thermoplastic elastomers, and is widely applied to applications requiring high durability. However, since there are limitations in the application of wide-ranging industrial groups due to their high weight, we tried to overcome this problem through the application of a supercritical fluid foaming system. In particular, carbon dioxide is a colorless, odorless, tasteless, inactive gas and other volatile gases, and it has the advantage of being relatively eco-friendly and capable of meeting lower supercritical fluid conditions. Therefore, the scCO2 application to TPU according to isocyanate type resulted in the development of the Expended TPU with excellent Resilience, C-Set and high expansion ratio. |
