Combined with FH series bio-based polyols, FH-31421 polyol is a high molecular weight triol which was developed for use in high resiliency molded foam formulations. Used in combination with graft polyols, such as FH-3973, it gives good processability even in low-density, high water formulations which can meet automotive seating requirements. FH-31421 is less reactive than FH-3945 and more reactive than FH-3538.
