Combined with FH series bio-based polyols, FH-3945 polyol is a high molecular weight polyol for use in high water, low-density automotive seating foams where a high degree of foam stability is required. In combination with graft polyols, such as FH-3152811, FH-3945 produces molded foams from high-water, low-density formulations. These foams are less susceptible to mold leakage, voiding and basal cells than foams produced with other polyols, but do require crushing to prevent shrinkage. FH-3945 is more reactive than either FH-3816 or FH-32097.
