A process and composition is described for the inclusion of polyether polyols in concentrations greater than 10% loading on the B-side formulation with a catalyst package less than 1% loading on the B-side formulation. In one specific example, the use of glycerin as a fluorine ion scavenger is utilized to improve performance of the polyurethane systems through a twelve-month shelf life.

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.

The invention relates to a composition for the production of foams based on phenolic resin, use thereof, and a process for the production of the composition. For provision of a composition for the production of foams based on phenolic resin, where the said composition delivers improved reaction to fire with, in essence, no alteration of further important foam properties, it is proposed that the composition comprises an alkoxylated novolak, wherein the novolak is produced using phenol, cresol and/or xylenol.
