Title: The Innovative Contributions of Sharon A. Free in Polymer Chemistry
Introduction
Sharon A. Free is a prolific inventor based in Wallingford, Pennsylvania, recognized for her substantial contributions to the field of polymer chemistry. With a total of nine patents to her name, Sharon has focused her research on developing advanced polyurethane foams that possess unique properties, enhancing their applicability in various industries.
Latest Patents
Among her latest innovations, Sharon's patents include a novel development in flame-laminable hydrophilic ester polyurethane foams. This foam is engineered to be flame laminated to a substrate using a thin sacrificial layer, which significantly enhances its properties. The sacrificial layer, typically less than 1.5 mm thick, is predominantly burnt away, resulting in a laminate that maintains excellent bond strength while preserving liquid wicking and absorptive capabilities.
Another noteworthy patent is the creation of felted hydrophilic ester polyurethane foams. This foam is formed through the reaction of polyester polyols with isocyanates and silicone surfactants, aided by a blowing agent. The resulting chemically treated foam demonstrates remarkable water absorption rates—up to 30 pounds of water per square foot per minute—along with superior water retention and strength compared to traditional cellulose materials.
