Title: The Innovative Contributions of Hans Jörg Hartmann
Introduction
Hans Jörg Hartmann is a notable inventor based in Olten, Switzerland. He has made significant contributions to the field of materials science, particularly in the production of foamed plastics. His innovative approach has led to advancements in the manufacturing processes of polyolefin-based materials.
Latest Patents
One of Hartmann's key patents is titled "Method for producing foamed plastic blocks based on polyolefin." This invention relates to a process for producing foamed polyolefin-based plastic blocks. The method involves crosslinking a matrix that consists of 51 to 97% by weight of one or more polyolefins, such as polyethylene and ethylene copolymer. Additionally, it includes 3 to 20% by weight of a foaming agent, which is activated using β-radiation of energy greater than 6 MeV. The matrix thickness ranges from 25 to 45 mm, and the radiation dose applied is between 20 to 150 kJ/kg. Importantly, during the irradiation process, atmospheric oxygen is substantially prevented from reaching the surface of the matrix. After crosslinking, the matrix is foamed by heating it to a temperature exceeding 160°C, which decomposes the blowing agent.
