TPU is a polymer material obtained by co-reacting a diisocyanate molecule such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) with a macropolyol or a low molecular polyol (chain extender).

Its molecular structure is a rigid block obtained by reacting diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) with a chain extender, and the molecular structure of diphenyl is diphenylmethane diisocyanate (MDI) or toluene. Rigid block obtained by reaction of diisocyanate (TDI) and chain extender and diphenyl
