Notizen:
A series of flexible urethane foams was formulated from diisocyanate-terminated polyether prepolymers, using both a polyether diol and an ethylenediamine tetraglycol as extenders. The long-term compression set characteristics and the compression deflection properties of these foams were studied. The swelling effect in a solvent, the free isocyanate content, and the role of a carbon black filler on the flexible urethane foam formulation were also evaluated. It was concluded that the total amount of diisocyanate used in the formulation, rather than a variation in the type of isocyanate, has the greatest influence on molecular structure.
