Soy polyol obtained from hydroxylation of soy
epoxide with ethylene glycol were prepared as prepolyurethane. The
two step process method were applied in the polyurethane synthesis.
The blending of soy polyol with synthetic polyol then simultaneously
carried out to TDI (2,4) MDI (4,4) (8020), blowing agent, and
surfactant. Ethylene glycol were not taking part in the polyurethane
synthesis. The inclusion of ethylene glycol were used as a control.
Characterization of polyurethane foam through impact resillience,
indentation deflection, and density can visualize the polyurethane
classifications.
