- W2355706829 abstract "Polyurethane(PU)elastomers were prepared with poly-e-caprolactone polyol,4,4'-diphenylmethane-diisoyanate(MDI)and mixture of 1,4-butanediol(BDO)and trimethylolprpane(TMP).The mechanical properties of the prepared PU elastomers were studied.The results showed that the mechanical properties of PU increased with the increase of mass fraction of NCO in prepolymer.When the content of TMP in chain extenders increased,the mechanical properties of PU decreased.When R0.95,the mole ratio of OH/NCO had obvious effect on the mechanical properties of PU.The tear strength and resilience of MDI-PU were better,but the tensile strength of TDI-PU was higher and the Comp.Set of TDI-PU was less with same hardness." @default.
