Preparation and Characterization of Novel Rigid Polyurethane Foams by Epoxidized Soybean Oil

Article Preview

Abstract:

A novel rigid polyurethane foam was prepared by using epoxidized soybean oil (ESBO) instead of 50% of petrochemical polyol-835 in the B-side of foam formulation. Although there are no significant variations in density and compressive strength of ESBO-based rigid foam compared with petrochemical-based rigid foam, better thermal stability and higher melting point (of polyether section) were attained and proved by TGA, DTG and DSC analysis. Presumably, the improved characterizations could be originated from the long carbon chain of ESBO and especially the oxazolidone structure as indicated in FTIR spectrum.
