Title: Takatoshi Toyama: Innovator in Emulsion Technology
Introduction
Takatoshi Toyama is a prominent inventor based in Ichihara, Japan. He has made significant contributions to the field of emulsion technology, holding a total of 5 patents. His work focuses on developing innovative compositions and methods that enhance the properties and applications of emulsions.
Latest Patents
One of Takatoshi Toyama's latest patents is an oil-in-water-type emulsion composition, which can be produced by directly emulsifying an organopolysiloxane with a high polymerization degree. This emulsion contains substantially no oversized particles and features a small average particle size. The method for producing this emulsion utilizes a vertical batch mixer, ensuring a consistent and high-quality product. The composition includes an organopolysiloxane with a viscosity of 1,000,000 mPa·s or more, a surfactant, and water. The average particle size of the emulsion particles ranges from 0.1 to 7.5 μm, with less than 5.0 vol% of particles being 10 times larger than the average size.
Another notable patent is for a sponge-forming liquid silicone rubber composition. This composition maintains a stable emulsified state and can create a low-density silicone rubber sponge with a uniform and fine open-cell foam structure. It is designed to minimize contraction during curing and achieve a density close to the intended design based on water content. The composition consists of an alkenyl group-containing organopolysiloxane, an organopolysiloxane with a silicon atom-bonded hydrogen atom, a mixture of water and an inorganic thickener, an emulsifier, and a hydrosilylation reaction catalyst, with component (C) comprising 70 mass% or more of the total composition.
