Latest Patents

One of Schuhmacher's latest patents is for a thermoplastic polyurethane elastomer blend and the process for its production. This invention is directed towards a thermoplastic polymer blend of polyurethane and nitrile rubber, achieving a Shore A hardness of about 55 to 70. The thermoplastic polyurethane component includes at least 50 weight percent polyisocyanate, while the nitrile rubber component contains approximately 34 mole percent acrylonitrile. The ratio between the thermoplastic polyurethane and nitrile rubber components is maintained between 30:70 to 40:60 volume percentage. The process for creating this blend involves mixing and kneading at temperatures ranging from 180°C to 215°C.

Another significant patent involves a method for preparing a latently reactive, pasty molding compound. This compound is designed to be reactive only above room temperature and is intended for manufacturing temperature-resistant, elasticized duromer molded components. It consists of a dimerized trimethylol propane and a low-molecular weight polyesterpolyol-diisocyanate-prepolymer, which can be fortified with fillers and is moldable at low pressures.
