Abstract: 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.

Abstract: A method of producing a closed-cell and rigid foam. The method comprises reacting an isocyanate composition including one or more polyisocyanates and a polyol composition including one or more polyols including one or more aromatic polyester polyols having a hydroxyl functionality of greater than 2 and one or more physical and/or chemical blowing agents including methylal to form a closed-cell and rigid foam configured to retain at least 85% of an initial volume of the closed-cell and rigid foam when exposed to about 97% relative humidity at about 70° C. for at least seven or more days.

Abstract: Hydrophobic silica is combined with a polyether in an in situ process for producing thermoplastic polyurethane with superior mechanical properties. The resulting thermoplastic polyurethane may be used in a variety of applications, including midsoles and outsoles in footwear and in wire insulation, hoses, films, wheels and tires, and drilling/mining screens.

Abstract: An article comprising two or more layers. One or more of the layers includes of a polymeric foam tape containing one or more curable resins. One aspect of the present invention is to use the article as an orthopedic casting splint.

Abstract: An article including a polymeric foam having a thickness of less than about 3/16 inch (about 5 mm) and one or more curable resins.

Abstract: A process for preparing polyol. The process can include depolymerizing an isocyanate-based material via a depolymerization reaction to obtain a liquid polyol product and treating the liquid polyol product with an adsorbent to remove an impurity from the liquid polyol product. The isocyanate-based material can be an isocyanate-based scrap material.

Abstract: An article including a polymeric foam having a thickness of less than about 3/16 inch (about 5 mm) and one or more curable resins.

Abstract: An orthopedic casting article comprising a polymeric foam tape containing one or more curable resins. The polymeric foam tape can be a foam having a substantially open cell structure, substantially closed cell structure, or a substantially reticulated cell structure. The curable resin can be a water-curable resin. The casting article can be multi-layered to obtain an article suitable for splinting applications.
