PUR foam modified by nanofillers

Abstract

This work focused to the possibility of PUR foam modified by inorganic nanofillers processing. As the source of nanoparticles was used untreated and treated type of montmorillonites. Ether type of polyurethane was employed to this experiment. Foams were prepared in a two step procedure. In the first step a fixed amount of montmorillonite was dispersed in polyols mixture. After filler dispersion in polyol, the catalysts, surface-active agent and blowing agents were added to the mixture. In the second step the isocyanate was added to the formulated polyol-filler mixture. The morphology of prepared samples was tested. It could be concluded, that suitable PUR foam was prepared with addition of inorganic nanofiller.
