  • Patent number: 7718102
    Abstract: Foam for making pads and belts with controlled, reproducible microcellular structure and method of making such foam in a fast and efficient manner. Under constant pressure and temperature, a prepolymer is mixed with the nucleation surfactant in a tank in the presence of a frothing agent metered into the tank by way of a dip tube or sparge. The nitrogen gas is sheared into small bubbles and is drawn off from the headspace of the tank creating a continuous flow of nitrogen. The pressure of the tank may vary from any absolute pressure down to near complete vacuum, thereby all but eliminating the pressure requirement. The froth of the present invention has a more consistent cell structure and increased cell count.

  • Publication number: 20080287561
    Abstract: Composites, such as syntactic foams, are described. The composite contains at least one polymer and at least one aerogel. The aerogel is coated with a coating substance to at least substantially prevent the intrusion of the polymer into the pores of the aerogel. Methods of making the composite are also described, as well as uses of the composite.

  • Publication number: 20080255262
    Abstract: The present invention is to a molded rigid polyurethane foam for application in appliance, having a reduced thermal conductivity at densities between 33 and 38 kg/m3 and a process for the production of such foams. The molded rigid polyurethane foam have a ratio of applied foam density (kg/m3) to lambda (mW/mK), measured at 10° C., 24 hours after foam production from 1.65 and to 2.15 and are obtained by the process of injecting into a closed mold cavity under reduced pressure a reaction mixture at a packing factor of 1.1 to 1.9 and the reaction mixture comprises: A) an organic polyisocyanate; B) a physical blowing agent, C) a polyol composition containing at least one polyol with a functionality of 3 or greater and a hydroxyl number between 200 and 800 and a water content of 0 to 2.5 weight percent of the total polyol composition; D) catalyst and E) auxiliary substances and/or additives.

  • Patent number: 7432311
    Abstract: A “high internal phase polymeric emulsion” (“HIPPE”) composition is described which comprises an emulsion of a discrete phase (component A) and a continuous phase (component B), wherein the volume fraction of the discrete phase is the majority fraction (on a volume basis) of the total volume of the emulsion. A compatibilizer, component C, is used to lower the interfacial tension between the phases containing components A and B. A process is described for creating such HIPPE composition in which the A component is a colloidal polymer particle.

  • Patent number: 7425288
    Abstract: A method for preparing an open pourous polymer material, comprises forming of a polymer solution, addition of a porogen to the polymer solution and precipitation with water of polymer from the polymer solution, and the method then comprises removal of solvent and porogen from the polymer material wherein the precipitation is homogenous through that the water is in form of crystal water and that the crystal water is bonded to the porogen, wherein the porogen is a sugar hydrate. An open porous polymer material, a mixture comprising a sugar hydrate and a polymer solution, and a designed material, and uses thereof are also disclosed.
