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: 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.
