摘要： A flexible polyurethane foam comprises up to 10 wt % of a fumed silica having a surface area from 50 to 150 m2/g, wherein the fumed silica has C1-C3 alkylsilyl groups at its surface, the flexible polyurethane foam exhibiting has a resilience of at least 40%, for example, from 40% to 70%, a dry compression set no greater than 15%, for example, from 3% to 15%, or both. Alternatively in addition, the flexible polyurethane foam may have a compression force deflection at 50% as measured by ASTM D3574 that is at least 30%, for example, at least 50%, at least 70%, or from 30% to 155%, greater than a flexible polyurethane foam having the same composition but with polyol replacing the silica.

摘要： Provided are a modified polyether polyol and the use thereof in polyurethane foam materials. The method for preparing a modified polyether polyol comprises the following steps: 1) reacting a compound A with a polyether polyol, wherein the compound A is an anhydride and/or dicarboxylic acid compound containing a polymerizable double bond, preferably selected from one or two of maleic anhydride and itaconic anhydride, preferably maleic anhydride; and 2) reacting the product obtained in step 1) with an epoxy compound containing a polymerizable double bond in the presence of a catalyst, in order to prepare the modified polyether polyol. The modified polyether polyol obtained by means of the preparation method has more active sites, uses the polymerizable double bond for blocking, is used as a dispersion stabilizer for the synthesis of copolymer polyols, and has the characteristics of a better dispersion stability, filterability and a low viscosity.

摘要： A cavity between inner and outer walls of an open-box-shaped mold is filled with a polyurethane reaction mixture, containing an isocyanate and an emulsion of an isocyanate-reactive composition with three polyols and a blowing agent, which is cured to a polyurethane containing polymer. The inner and outer wall are a fixed distance from one another and each wall comprises a bottom and sides. The mixture is fed through an inlet in the bottom of the outer wall. Before filling the cavity, the mold is turned downwards so that the mixture foams upwards, filling the cavity. The three polyols are polyether polyol obtained by adding an epoxy to carbohydrates or difunctional or higher-functional alcohols; polyether polyol obtained by adding an epoxy to an aromatic amine; and polyester polyether polyol obtained by adding an epoxy to the esterification product of an aromatic dicarboxylic acid derivative and a difunctional or higher-functional alcohol.
