Latest Patents
Yokota's latest patents include two groundbreaking inventions. The first is titled "Ultra high molecular weight concurrently sintered and cross-linked." This invention involves 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, providing 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 outlines the production of accurately sized sintered material of ultra high molecular weight polyethylene. It includes steps such as 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 of the mixture exhibits extremely small transverse dimensional accuracy, ensuring highly accurate size and roundness, along with uniform electroconductivity.
