    Abstract: Embodiments of the invention describe methods and apparatus for mixing chemical components in the manufacture of polyurethane foam. The chemical components include a polyol and different blowing agents. The blowing agents are injected directly into a mixing chamber (100) at different height levels according to their boiling points. The mixing chamber allows continuous discharge of the mixture into a static mixer (400) for further mixing before being stored into a storage tank (600). The blowing agents are chemical compounds selected from the group consisting of hydrocarbon-containing compounds, hydrofluorocarbon-containing compounds or hydrofluoroolefin-containing compounds.

    Abstract: A viscoelastic foam system is provided having an amine-based polyoxypropylene extended polyol to impart strength, recoverability and endurance to the foam, and an appropriately selected non-amine-based polyol to provide flexibility to the foam. The combination of amine-based propylene oxide extended polyol and non-amine-based polyol provides a viscoelastic semi-rigid foam with excellent impact and recovery properties, recovering to substantially 100% of its initial volume and shape following an impact, yet with sufficient rigidity and stiffness so that it is effective at absorbing multiple impacts. A method of making the above viscoelastic foam is also provided.

The combination of amine-based and non amine-based polyols provides a viscoelastic semi-rigid foam with excellent impact and recovery properties, recovering to substantially 100% of its initial volume and shape following an impact, yet with high rigidity and stiffness so that it is effective at absorbing high as well as low-energy impacts. A method of making the above viscoelastic foam is also provided. In a preferred embodiment, the foam is made using an allophanate-modified MDI prepolymer in order to provide the isocyanate in liquid form at standard temperature and pressure in order to simplify the production of the invented viscoelastic foams.

  • Patent number: 7056957
    Abstract: The present invention features a method for the formation of superporous hydrogels using an ion-equilibration technique. Anionic polysaccharides are included in the hydrogel reaction mixture and cations are introduced either during or after hydrogel formation. Properties of the resulting hydrogel can be subsequently adjusted by treating the cation-complexed gel with a different cation or cation mixture under equilibrating conditions. It has been found that by properly adjusting the cations and the sequence in which they are used in the equilibration process, superporous hydrogels can be formed that are highly absorbent while maintaining favorable structural properties, including strength, ruggedness, and resiliency. It has also been found that applying appropriate dehydration conditions to them after their formation can further stabilize the superporous hydrogels formed by the method of the invention.

  • Patent number: 6670405
    Abstract: The invention relates to a method for producing block-shaped and plate-shaped polymethacrylimide foamed materials by copolymerizing methylacrylic acid and methylacryl nitrile, by subjecting the copolymerizate to a post-polymerization and cyclization in order to form polyimide, and by converting the same into a foamed material. The invention is characterized in that the copolymerization is carried out in the presence of a mixture containing at least three initiators with graduated half-life periods. The polymerization can be controlled especially well and yields polymerizate plates with thicknesses of up to 80 mm which can be easily foamed. The invention makes it possible to produce filling materials, especially plates and blocks containing electrically conductive particles.

  • Patent number: 6458859
    Abstract: By blending acicular conductive titanium oxide and an antistatic agent having a metal ion-containing moiety in an organopolysiloxane having at least two aliphatic unsaturated groups, there is obtained a silicone rubber composition which is curable with an organic peroxide and/or an organohydrogenpolysiloxane/platinum group catalyst. The composition cures into silicone rubber having a stabilized resistivity in the semiconductive region, especially in the range of 1×103 to 1×1012 &OHgr;-cm, even under high voltages. The composition is thus suitable as a semiconductive roll material for use as charging rolls, transfer rolls and developing rolls.
