Title: Innovations by Joseph Pleckaitis: Advancements in Thermoplastic Polyurethanes
Introduction
Joseph Pleckaitis, an accomplished inventor based in North Haven, Connecticut, has made significant contributions to the field of thermoplastic polyurethanes. With two patents to his name, his work has focused on enhancing processing capabilities and performance characteristics of these versatile materials.
Latest Patents
Joseph Pleckaitis's latest inventions include two notable patents that address critical aspects of thermoplastic polyurethane elastomers. The first patent details the preparation of thermoplastic polyurethanes with small amounts of monohydric aliphatic alcohol. This innovative approach reduces processing temperatures, enhances extrudability, and minimizes sensitivity to degradation caused by shear and moisture. Specifically, by incorporating a minimal proportion of the alcohol in the reaction mixture, which consists of diisocyanate, polymeric diol, and difunctional extender, Pleckaitis has optimized the one-shot procedure for manufacturing these elastomers.
His second patent focuses on polyurethane elastomers based on alcohol-modified diisocyanate. This invention utilizes a diisocyanate that results from the reaction of 4,4'-methylenebis(phenyl isocyanate) with a monohydric aliphatic alcohol. This process not only lowers processing temperatures and improves extrudability but also addresses batch-to-batch variations in reactivity, further streamlining production and ensuring consistent quality.
