Thermal degradation of fiber-reinforced bio-based rigid polyurethane foams Documento de la Conferencia uri icon


  • Rigid polyurethane (PU) foams were prepared by a multistep procedure using a polyol blend of poly(ethylenglycol) PEG-200/pineapple molasses, and 4,4'-diisophenylmethane diisocyanate (MDI), with a NCO/OH ratio of 1.2. Such material was reinforced with fibers from banana rachis, with a fiber composition ranging from 18% to 40% wt. Thermal, and themooxidative degradation properties of these composites were assessed. Thermal degradation of PU60 showed the highest polymer lifetime values.
