| Abstract: | A polyurethane(PU)rigid foam was prepared, using PAPI and the polyether polyols deried from starch ethylene glycol glycoside(EGG)as the main materials, and the foaming processing was studied. The water blowing foam formulation was designed and the structure and properties of PU were investigated by mechanical tests. The studies indicated that the foam formulation without CFC-11 was successful. It was found that the rigid foam PU had good mechnical properties and thermal conductivity. |
