Abstract: The thermal conductivity and specific heat of seven different polyurethane foams and their melts were investigated using the Transient Plane Source. The thermal conductivity of the foams themselves ranged between 0.048 and 0.050 W/mK, while the thermal conductivity of the melt product was 0.186 to 0.200 W/mK, a difference of 300%. Melting had the opposite effect on the specific heat of the samples, which dropped 20% from a range of 2359 to 2996 J/kgK to 1958 to 2076 J/kgK.
