Title: Robert Hartwimmer: Innovator in Free-Flowing Sintering Powders
Introduction: Robert Hartwimmer, an accomplished inventor based in Burghausen, Germany, has made significant contributions to the field of polymer science, specifically in the development of free-flowing sintering powders. With a portfolio of six patents, his work has enhanced the properties and applications of these materials.
Latest Patents: Hartwimmer's latest innovations focus on the production of free-flowing sintering powders that contain at least 98.5% by weight of tetrafluoroethylene units. These powders are created from colloidal polymer dispersions through emulsion polymerization. The process involves initial stirring with the optional addition of inorganic salts until thickening occurs, followed by the addition of an organic liquid that is minimally soluble in water. This meticulous method allows for the production of granules with high bulk density and excellent flow properties. These sintering powders are versatile, suitable for ram extrusion and press-sinter processing, ultimately producing sintered blocks and veneer-cut films.
Career Highlights: Throughout his career, Robert Hartwimmer has demonstrated a commitment to innovation in polymer chemistry while working with Hoechst Aktiengesellschaft. His expertise in developing advanced materials has positioned him as a key figure in the industry, with patents that reflect his deep understanding of polymer behaviors and properties.
Collaborations: Hartwimmer has worked alongside notable colleagues such as Jurgen Kuhls and Reinhard Albert Sulzbach. These collaborations have allowed for the exchange of knowledge and ideas, further enriching the development of their innovative projects.
Conclusion: Robert Hartwimmer's work in the realm of free-flowing sintering powders not only exemplifies his inventiveness but also highlights the potential of polymer materials in industrial applications. His contributions serve as a testament to the importance of research and development in advancing technology and improving material properties.
