Summary

Starch-based polyurethane foams were synthesized in a reaction of polyol blend derived from microwave assisted liquefied corn starch product and chemically recycled polyol from cold cured polyurethane foam waste, in blending with virgin one polyol with MDI as an isocyanate portion. The effect of microwave irradiation program was investigated in the starch liquefaction and recycling of polyurethane foam waste processes in order to achieving optimum conditions. Reactivity factors, densities and thermal properties of synthesized starch/recycled polyol based foams were investigated and results revealed the performances in thermal resistivity of prepared foam with containing 45 % of recycled polyol in comparison with foam obtained from virgin polyol alone and without starch/recycled polyol.


Key words: starch, polyurethane foam waste, microwave assisted reactions, starch liquefaction
