Effect of the Starting NCO/OH Molar Ratio on the Structure and Properties of Polyurethane
Abstract:
The present study described the effect of the starting NCO/OH molar ratio on the structure and properties of castable polyurethanes based on polytetrahydrofuran glycol (PTMG) and 2,4- toluene diisocyanate (TDI). The structural was tested by SEM. The result showed that higher starting NCO/OH molar ratio can lead to higher degree of microphase separation, decrease the compression set and improve the dynamic mechanical properties.
