Title: Yoshitaka Eto: Innovator in Polyester Resin Technology
Introduction
Yoshitaka Eto is a prominent inventor based in Otsu, Japan. He has made significant contributions to the field of polyester resin technology, holding a total of 2 patents. His work focuses on developing innovative materials that enhance the performance and usability of polyester resins in various applications.
Latest Patents
Yoshitaka Eto's latest patents include a polyester resin composition and a reduced pressure blood-collecting tube. The polyester resin composition comprises (A) 10 to 90% by weight of a polyethylene terephthalate polymer with 100 to 75 mole % of ethylene terephthalate units and (B) 90 to 10% by weight of a polyester resin. This composition, when molded into a sheet, exhibits an oxygen permeability coefficient of 3.0 or less cc-mm/m, day·atm. The resulting molded product is outstanding in transparency, gas barrier property, ultraviolet-screening property, and impact strength, making it suitable for use as a reduced pressure blood-collecting tube.
Another significant patent involves a polyester resin characterized by a polyester resin chip (A) and a polyester resin fine particle (B) with the same composition as (A). This fine particle passes through a 10.5 mesh screen in a proportion of 0.1-300 ppm. The invention ensures that the cyclic trimer increases in proportion of not more than 0.30 wt % upon melting at a temperature of 290°C for 60 minutes. The polyester resin's composition also limits the contents of Na, Ca, Mg, and/or Si to 0.001-5 ppm, ensuring superior quality and performance.
