Title: Werner Gey: Innovator in Polyester Production
Introduction
Werner Gey is a notable inventor based in Offenbach, Germany. He has made significant contributions to the field of polymer technology, particularly in the production of polyester for food packaging. With a total of 3 patents to his name, Gey's work has had a substantial impact on the industry.
Latest Patents
One of Gey's latest patents is a process for the production of polyester polymer for food packing. This innovation involves creating polyethylene terephthalate with an acetaldehyde content of less than 2.5 ppm, making it suitable for packaging food and beverages intended for human consumption. The process requires heating polyethylene terephthalate with an intrinsic viscosity of about 0.5–0.85 at temperatures ranging from 180°C to 230°C, preferably between 200°C and 220°C, for a duration of 4 to 12 hours. It is crucial that the polyethylene terephthalate does not contain more than 25 ppm of ester interchange catalyst or 20 ppm of phosphorous during this heating process.
Another significant patent by Gey focuses on the solid-state polycondensation of linear polyesters. In this process, a separating or anticaking agent made of spherical glass particles with a diameter of 3 to 30 micrometers is added to polyester resin granulates. This addition prevents agglomeration during solid-state polycondensation in a plug-flow reactor. The thin-walled articles produced from this end product exhibit high strength, transparency, crystal clear color, good gas impermeability, and a smooth surface.
