Abstract: Modified 2,4-toluene diisocyanate (2,4-TDI) and 2,6-toluene diisocyanate (2,6-TDI) isomer mixtures and methods of producing the modified TDI isomer mixtures are provided. The modified TDI isomer mixture is a low-cost alternative to expensive commercially available TDI mixtures with high 2,6-TDI ratio, and produce a flexible PU foam with desirable foam properties.
