A technical bulletin on the use of Santicizer benzyl phthafate and alkyl diphenyl phosphate ester polymer modifiers in flexible polyurethane foam applications is available from Monsanto. The bulletin is a comprehensive look at how Monsanto’s polymer modifiers can control foam firmness in water-blown systems, without sacrificing other performance characteristics. The information shows the effect of the polymer modifiers on water-blown, MDI-based, flexible polyurethane foam, generally considered the most difficult system to soften. TDI-based foam properties also benefit by use of these polymer modifiers.
