Introduction

Susumu Izawa is a prominent inventor based in Utsunomiya, Japan. He has made significant contributions to the field of polyolefin resin technology, holding a total of 5 patents. His innovative approaches have advanced the methods of producing and treating polyolefin resin particles.

Latest Patents

One of his latest patents is a production method of prefoamed particles of polyolefin resin. This method involves dispersing starting particles of polyolefin resin, which contains a volatile foaming agent, in a dispersant within a pressure vessel. The dispersion is then heated to a temperature at least at the softening point of the starting particles. The vessel is opened at one end to release the starting particles and dispersant into an atmosphere of lower pressure, while feeding a heating liquid. Another notable patent is a heat treatment apparatus for polyolefin resin particles. This apparatus features an autoclave where the particles are heated and agitated in the presence of an aqueous medium and dispersing agent. The autoclave is designed with a tilted bottom wall portion, equipped with a turbine-type impeller for effective mixing.
