Title: Shigeru Iseki: Innovator in Fluorocarbon Polymer Technology
Introduction
Shigeru Iseki is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of polymer technology, particularly in the development of methods for agglomerating polytetrafluoroethylene powder. With a total of 2 patents to his name, Iseki's work has had a notable impact on the industry.
Latest Patents
Iseki's latest patents include a method of agglomerating polytetrafluoroethylene powder. This innovative technique involves finely ground polytetrafluoroethylene molding powder being subjected to high-speed agitation in the presence of a medium consisting of water and a hydrophobic organic liquid. The specific ratio used is 0.5 to 1 liter of the medium per 1 Kg of the resin. The hydrophobic organic liquids used in this process dissolve less than 15 wt. % in water at the temperature of agglomeration. The volumetric ratio of the organic liquid to water ranges from 2 to 1/2. This method results in an agglomerated product with a narrow particle size distribution, high bulk density, and free-flowing properties achieved through short agitation times. Another significant patent involves a fluorocarbon polymer composite that comprises a fluorocarbon polymer and a treated filler, which can be in various forms such as powder, granules, beads, fiber, or fabric sheet, treated with polyphenylene sulfide.
