Title: Innovation in Sliding Materials: The Invention of Atsuko Hirose
Introduction: Atsuko Hirose, a pioneering inventor based in Kiyosu, Japan, has made significant contributions to the field of materials science. With a focus on the production of sliding materials for weather strips, her innovation offers a blend of advanced materials that enhance performance and durability.
Latest Patents: Atsuko holds a patent for the "Method of producing sliding material for weather strips." This innovative process involves feeding polypropylene (PP), ethylene propylene diene monomer (EPDM) prior to crosslinking, and polyethylene (PE) particles into a twin-screw extruder. The approach ensures that EPDM is dynamically crosslinked, resulting in a sliding material composed of an olefin-based Thermoplastic Vulcanizate (TPV) with dispersed PE particles. The formulation allows for a specific ratio, where PE particles are blended in amounts ranging from 10 to 90 parts by mass relative to 100 parts by mass of the total PP and EPDM. It is essential for the PE particles to have an average particle diameter of 30 to 200 micrometers before feeding, which are then micronized during the melt kneading to achieve a diameter of 10 to 50 micrometers in the final product.
Career Highlights: Atsuko Hirose has established her career at Toyoda Gosei Co., Ltd., a leading manufacturer of automotive components. In her role, she has been instrumental in advancing technologies related to weatherstripping materials, focusing on the intersection of performance and sustainability within automotive applications.
