Fabrication of rigid flame retardant foam using bio-based sucrose-furanic resin for building material applications
As sucrose is less expensive and more readily available than tannin, sucrose-based foams were prepared by incorporating furfuryl alcohol (FA) and glyoxal as a crosslinking agent to obtain sucrose-furan-glyoxal (SFG) resin. Ammonium dihydrogen phosphate (ADP) was then incorporated into SFG and foamed...

As sucrose is less expensive and more readily available than tannin, sucrose-based foams were prepared by incorporating furfuryl alcohol (FA) and glyoxal as a crosslinking agent to obtain sucrose-furan-glyoxal (SFG) resin.
