Chemical modification of tannin/furanic rigid foams by isocyanates and polyurethanes

Show other versions (1)

Tannin/furanic rigid foams were modifi ed by either polymeric 4,4’ diphenylmethane diisocyanate (pMDI) or a one-component polyurethane still presenting reactive isocyanate groups (PUR). Several diff erent sequences of mixing the isocyanate and polyurethane with the chemicals used to prepare tannin-b...
