This paper presents the idea of flavonoid foams that are manufactured from natural resources rather than formaldehyde-containing tannin-based foams. A TPS instrument measured the thermal conductivity of the foams using the transient plane source (TPS) technique. Results show that the flavonoid foams are a better choice than tannin-based foams because they have a lower thermal conductivity which makes them more insulative and fire resistant, and they do not release toxic ...
