Abstract Tannin/furanic foams, typically 95% composed of materials of natural origin such as prorobinetinidin/
profi setinidin tannins and furfuryl alcohol, are potential alternatives to oil-based synthetic foams such as
phenol-formaldehyde, and polyurethane foams. This article describes the development of second generation
tannin/furanic foams, which are not only formaldehyde free, but also use nonvolatile, nontoxic aldehydes.
Both glyoxal and glutaraldehyde were tried to substitute formaldehyde in tannin/furanic foams. The physical
properties of these new foams are described and discussed. It was found that glutaraldehyde can totally
substitute formaldehyde during tannin/furanic foam preparation, but that glyoxal cannot. The optimized
proportion to prepare such… More >
