Polyurethane with shape memory change from foil to foam when heated

Researchers at the Fraunhofer Institute for Applied Polymer Research IAP have developed a foil that changes into polyurethane foam (PU foam) when heated—entirely without health risks. The foil allows for isocyanate-free foaming, thus improving workplace safety. Additionally, it offers logistics advantages for storage and transportation. The material can be customized for various applications ranging from the automotive and construction industries to packaging.
