Flexible polyurethane nanocomposite foam: Synthesis and

Flexible polyurethane (PU) nanocomposite foams were synthesized using organically modified montmorillonite clay (Cloisite 30B). The dispersion of organoclay was considered both in the isocyanate and polyol matrixes. Silicate layers of organoclay can be exfoliated in PU matrix by use of two steps mixing process. The presence of clay increased the cell density and reduced the cell size compared ...
