Title: Masaaki Yamamoto: Innovator in Ultra High Molecular Weight Polyethylene
Introduction
Masaaki Yamamoto is a notable inventor based in Amagasaki, 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, his work has advanced the understanding and application of this versatile material.
Latest Patents
Yamamoto's latest patents include innovative methods and products that enhance the properties of ultra high molecular weight polyethylene. One of his key inventions is the "Ultra high molecular weight concurrently sintered and cross-linked" product. This invention involves a ram extruded product formed by a mixture of ultra high molecular weight polyethylene powder, 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 provide adequate conductivity without adversely affecting the mechanical properties of the product.
Another significant patent is the "Method of producing accurately sized material of ultra high molecular weight." This method outlines the steps for producing sintered material with precise dimensions. It involves mixing an organic peroxide and a lubricant with ultra high molecular weight polyethylene powder, which has a mean molecular weight exceeding 1,000,000. The resulting ram extrusion exhibits extremely small transverse dimensional accuracy, ensuring high precision in size and roundness, along with uniform electroconductivity.
