Title: The Innovations of Ernst Lohmar
Introduction
Ernst Lohmar is a notable inventor based in Weinheim, Germany. He has made significant contributions to the field of materials science, particularly in the development of polyurethane foam technologies. With a total of five patents to his name, Lohmar's work has had a considerable impact on various industries, especially in automotive applications.
Latest Patents
One of Lohmar's latest patents is focused on a polyvinyl chloride-free plastisol. This innovative material comprises polyurethane soft foam that exhibits sound insulating and vibration damping properties. The invention involves reacting polyisocyanate or polyisocyanate prepolymers with an excess of polyols while maintaining a specific NCO index. The resulting foam has an adhesive surface and is characterized by a density ranging from 80 to 250 kg/m³, a modulus of elasticity of less than 300,000 N/m², and a loss factor of at least 0.4. This production process is ideally executed using a RIM machine, making the foam particularly suitable for use in vibration damping sound insulation systems in automobiles.
