Solid polyurethane tire/wheel assembly

A substantially solid industrial polyurethane tire/wheel assembly where said polyurethane is prepared by reacting (A) a curative of 1,3-propane diol with a prepolymer of diphenylmethane-4,4'-diisocyanate and a polymeric polyol or (B) a curative complex of 4,4'-methylene dianiline with a pr...

Beschreibung
Zusammenfassung:	A substantially solid industrial polyurethane tire/wheel assembly where said polyurethane is prepared by reacting (A) a curative of 1,3-propane diol with a prepolymer of diphenylmethane-4,4'-diisocyanate and a polymeric polyol or (B) a curative complex of 4,4'-methylene dianiline with a prepolymer of a diisocyanate selected from diphenylmethane-4,4'-diisocyanate and toluene diisocyanate with a polymeric polyether polyol. It is an important feature of this invention that the selection of reactants involved, for the dianiline complex, a partial substitution of the polyether polyol with a polyether-ester polyol.
