Title: Kazuhiro Yamamura: Innovator in Fluororubber Technology
Introduction
Kazuhiro Yamamura is a prominent inventor based in Settsu, Japan. He has made significant contributions to the field of materials science, particularly in the development of advanced fluororubber compositions. With a total of seven patents to his name, Yamamura's work has had a considerable impact on various industrial applications.
Latest Patents
One of Yamamura's latest patents is a fluororubber composition that provides a crosslinked fluororubber article exhibiting both heat resistance and excellent mechanical properties at high temperatures. This composition includes a fluororubber (A), a carbon black (B), and an aromatic petroleum resin (E). The unique properties of this composition are characterized by a difference δG′ (G′ (1%)−G′ (100%)) that ranges from not lower than 120 kPa to not higher than 3,000 kPa. The shear modulus values are determined through a dynamic viscoelasticity test conducted on unvulcanised rubber.
Another notable patent involves a core-shell type particle that consists of a core containing a perfluoropolymer and a shell made of a non-fluorine resin. The core is coated with the non-fluorine resin at a coverage of 90% or more. The perfluoropolymer is composed of a polymerized unit based on a perfluoro monomer, making up 90 mol % or more of all polymerized units. The shell's mass is limited to 50 or less relative to the total mass of the core and shell, which is capped at 80. This innovation also includes a method for producing the core-shell particle.
