Title: Fumio Matsuoka: Innovator in Ultra High Molecular Weight Polyethylene
Introduction
Fumio Matsuoka is a notable inventor based in Kobe, Japan. He has made significant contributions to the field of materials science, particularly in the development of ultra high molecular weight polyethylene products. With a total of 2 patents, Matsuoka's work has advanced the understanding and application of this versatile material.
Latest Patents
Matsuoka's latest patents include two innovative inventions. The first is titled "Ultra high molecular weight concurrently sintered and cross-linked." This invention describes a concurrently sintered and cross-linked ram extruded product formed by a mixture of ultra high molecular weight polyethylene powder with a cross-linking agent, an electrically conductive agent, and a lubricant. Remarkably, as little as 0.5 parts per 100 parts of polyethylene of the electrically conductive agent can be added to the ultra high molecular weight polyethylene powder. This addition provides adequate conductivity without adversely affecting the mechanical properties of the product.
The second patent is "Method of producing accurately sized material of ultra high molecular weight." This method involves mixing an organic peroxide and a lubricant with ultra high molecular weight polyethylene powder, which has a mean molecular weight of more than 1,000,000 by a viscosity method and more than 3,000,000 by a light scattering method. The process results in a ram extrusion of the mixture, achieving extremely small transverse dimensional accuracy. This ensures that the extruded product has highly accurate size and roundness, along with uniform electroconductivity.
