Title: Keisuke Suzuki: Innovator in Polyester Technology
Introduction
Keisuke Suzuki is a prominent inventor based in Iwakuni, Japan. He has made significant contributions to the field of polyester technology, holding a total of 2 patents. His work focuses on the development of advanced polyester materials that enhance processing capabilities and product quality.
Latest Patents
Keisuke Suzuki's latest patents include the "Amorphous Polyester Chip and Method for Production Thereof" and the "Method for Storage of Amorphous Polyester Chip." The amorphous polyester chip is characterized by a moisture content of not more than 300 ppm and a fine particle content of not more than 500 ppm. A preferred embodiment of this invention is a copolymerized polyester chip that consists of a main repeating unit made from ethylene terephthalate and either 1,4-dimethylene-cyclohexane terephthalate or neopentyl terephthalate. The glycol component of the copolymerized polyester has a specific composition that includes 50 to 85 mol % of ethylene glycol, 12 to 45 mol % of 1,4-cyclohexanedimethanol or neopentyl glycol, and 1.5 to 7.0 mol % of diethylene glycol. This innovative chip can be produced by cooling an amorphous polyester obtained through melt polymerization, cutting it into chips, and then drying the chips while removing fine particles.
Another significant patent is the "Polyester Resin and Production Method Thereof." This invention involves a polyester resin that comprises a polyester resin chip (A) and a polyester resin fine particle (B) with the same composition as (A). The resin is designed to minimize staining in molds during the production of formed articles, resulting in hollow products that exhibit superior transparency and heat resistance.
