Chemical modification of tannin/furanic rigid foams by isocyanates and polyurethanes
Tannin/furanic rigid foams were modified by either polymeric 4,4’ diphenylmethane diisocyanate (pMDI) or a one-component polyurethane still presenting reactive isocyanate groups (PUR). Several different sequences of mixing the isocyanate and polyurethane with the chemicals used to prepare...
