Abstract: Disclosed are a foaming material, a thermal insulation cabinet, and preparation methods therefor. The foaming material comprises 100 parts of a combined polyol, 10-30 parts of a foaming agent composition, and 120-150 parts of an isocyanate. In the present invention, the type of the polyol used in a foaming system is adjusted in order to increase the content of a polyester polyol and reduce the content of a polyether polyol, such that the compressive strength of the foaming material is significantly improved without increasing or changing the injection amount.

Abstract: 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.
