The main objective of this research project funded by MINECO is to develop a family of multifunctional additives for polymeric foams. Those additives will be based on the combination of funtionalised nanosepiolites with other active elements capable of improving, at the same time, the thermal insulation, mechanical and fire resistance properties of the foams under study. NEOADFOAM project will focus on two materials widely employed as thermal insulators in the construction industry: expanded polystyrene and rigid polyurethane foams. The solutions that will be developed aim to provide turnkey answers to foam producers (target market) in order to improve the added value of their products.
