Process for flexible polyurethane foam manufacture via separate and variable component mixing of at least 3 separate component streams, where at least one of the streams is TDI and one other stream is a preferred composition of MDI. Further provided is an empirical method for determining the level of TDI over a wide range of water levels and formulation compositional differences.
