Title: Innovations of Toru Yamamoto

Introduction

Toru Yamamoto is a notable inventor based in Kanuma, Japan. He has made significant contributions to the field of plastic foam production, holding 2 patents that showcase his innovative approaches.

Latest Patents

Yamamoto's latest patents include a "Process and apparatus for extruding plastic foams through a fluorocarbon." This method involves producing a plastic foam of a desired expanded dimension by extruding a melt of thermoplastic synthetic resin containing a blowing agent. The extrudate is then passed through a shaping device, which is secured to the discharge end of the extruder. An improvement in this process is the use of a fluorocarbon resin plate on the inside surface of the shaping device, allowing for better expansion and solidification of the molten mass.

Another significant patent is the "Process for producing foamed polystyrene boards." This process involves melting polystyrene in an extruder, mixing it with a blowing agent, and extruding the resulting foamable molten gel. A unique feature of this patent is the inclusion of a flowability improver with a melting point higher than 70°C, which enhances the extrusion formability of the foam. The resulting foam exhibits excellent dimensional stability, high mechanical strength, and superior thermal insulation properties.
