Polyurethane foams are described, as well as the production of such polyurethane foams by the reaction between a natural polyol, such as sucrose or a blend of mono- or disaccharides in place of the standard hydrocarbon-based polyol component, an ionic liquid or a deep eutectic solvent, a polyisocyanate and water in the presence of a suitable polyurethane forming catalyst and optionally a flame retardant, and optionally one or more components such as surfactants and/or emulsifiers. The resultant polyurethane foam can exhibit a bio-based solid content ranging from about 17% to 30%, may be formulated in a variety of foam densities for a variety of applications, and in the instance where a flame retardant has been added in an appropriate amount, exhibits a high degree of fire and burn resistance, as exhibited by the flame spread index and/or the smoke spread values.

Polyurethanes, polyurethane foams and methods for their manufacture

Polyurethane foams which are highly flame resistant are described, as well as the production of such polyurethane foams by the reaction between a natural polyol, such as sucrose or a blend of mono- or disaccharides in place of the standard hydrocarbon-based polyol component, a polyisocyanate and water in the presence of a suitable polyurethane forming catalyst and a non-halogenated flame retardant, and optionally one or more components such as surfactants and/or emulsifiers. The resultant polyurethane foam has a bio-based solid content ranging from about 17% to 30%, may be formulated in a variety of foam densities for a variety of applications, and exhibits a high degree of fire and burn resistance, as exhibited by the flame spread index, flash over resistance determination, and the smoke spread values.
