Abstract: Non-isocyanate polyurethane (NIPU) have the potential to replace polyurethane (UP) foams in the future. This study attempts to synthesize non-isocyanate polyurethane (NIPU) at room temperature for the first time. A TPS instrument measured the thermal conductivity of the foams using the transient plane source (TPS) method. Results showed that foams prepared with 10 or 20% of PPOBC640 had the highest thermal conductivities. NIPU foams had a slightly higher thermal conductivity than PU foams, but their lower thermal diffusivity makes them promising insulators that could potentially replace PU foams.
