Title: The Innovative Contributions of Masashi Shimakage in Rubber Composition
Introduction: Masashi Shimakage, an eminent inventor from Yokkaichi, Japan, has made notable strides in the field of synthetic rubber. With a keen focus on enhancing material properties, his work continues to influence various industrial applications.
Latest Patents: Masashi Shimakage holds a patent for an innovative ethylene-alpha-olefin-non-conjugated diene copolymer rubber composition. This advanced formulation comprises two types of ethylene-alpha-olefin-non-conjugated diene copolymers, referred to as copolymers (A) and (B). Copolymer (A) includes ethylidenenorbornene combined with either dicyclopentadiene or alpha,omega-diene having 8 to 20 carbon atoms in the main chain. In contrast, copolymer (B) utilizes ethylidenenorbornene as the non-conjugated diene. The weight ratio of copolymer (A) to copolymer (B) is designed to be between 30/70 and 70/30, enabling the copolymer (A) to possess a relatively low molecular weight and specific material properties. This unique rubber composition exhibits exceptional performance characteristics, such as excellent shape retention during cross-linking, minimal reduction in low tensile stress upon foaming, and favorable processability.
