ABSTRACT
Polyurethane foams, flexible or rigid in nature, were developed as early as in the 1930s. Since then, they have been established in numerous extensive as well as intensive applications, especially in the post World War II period. The main feature of a PU foam is its capability to deliver a wide range of densities, cell structures, foam morphologies, and rigidity, controlled solely by formulation adjustments. The key markets and applications for PU foams are listed in Table 6.1.
