  • Patent number: 9902827
    Abstract: A method for continuously preparing solvent-free open-cell and closed-cell polyimide foams, firstly, one or a few of dianhydrides dissolve in or suspend in the polyhydric alcohol and form the precursor A. All kinds of additives dissolve in the polyhydric alcohol and form the precursor B. The aromatic isocyanates with different structure mix well and form the precursor C. Finally the three precursors are mixed foaming by one-step, after solidify, the polyimide foams are obtained with advantage performance. The method does not utilize the volatile solvent that does not participate in the reaction, therefore not existing the process of removing the solvent, it can continuously produce with the double-side heat conveyor belt. CO2, the main gas producing in the reaction, causes the system to foam, thus there is no cost on the solvent recovery and it reduces the environment contamination.

  • Publication number: 20140039077
    Abstract: A flexible polyurethane foam with improved resistance to discoloration from oxidation is disclosed. Such discoloration may be due to exposure to oxides of nitrogen, for example, the oxides commonly found in burnt gas fumes. The foam may be used for applications such as intimate apparel and other consumer products that need extended term color stability. The foam composition includes high levels of reactive and non-reactive phosphite esters that improve color stability without disadvantage to the foam's physical and aesthetic properties during and after production.

    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 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 and the smoke spread values.
