Polyflavenoid tannin-furanic rigid foams have widespread industrial applications. The chemical and physical properties of the five main tannin-based foams are tested and compared in this paper. A TPS instrument measured the thermal conductivity of the tannin-based foams using the transient plane source (TPS) method. Results showed that the tannin foam containing formaldehyde and a low-boiling blowing agent (STD) had the highest thermal conductivity, and the foams without formaldehyde and surfactant (...
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 ...
The first soy and tannin based organic aerogels with 91% naturality have been developed by researchers, and they have low bulk density but high volumes of mesopores. In this experiment, the transient plane source (TPS) method was used to measure the thermal characteristics of the organic aerogels. Results showed that these novelty aerogels are ecologically friendly because they are low cost and renewable but have attractive thermal properties....
The authors set out to prepare cellular vitreous carbon (CVC) foams with varying thermal and physical properties. This was accomplished by using tannin-based resin modified by different isocyanates in varying amounts. Three different experimental procedures were used to prepare foams with different physical and thermal properties. Physical properties of the foams studied include density, as well as pore volume, pore size and cell diameter. The transient plane source (TPS) technique ...
