Title: **Innovative Contributions of Katsuyuki Usami in Thermoplastic Resin Technology**
Introduction
Katsuyuki Usami, an accomplished inventor based in Yokohama, Japan, has made significant strides in the field of materials science. With a commendable portfolio that includes two patents, he has focused on advancing thermoplastic resin technology, particularly in applications for packaging and electronic displays.
Latest Patents
Usami's most recent patents reflect innovative processes in the production of polypropylene and thermoplastic resin sheets. His first patent introduces a polypropylene sheet designed specifically for press-through packages. This sheet is formed from a resin composition, which includes a polypropylene resin and a hydrogenated petroleum resin blended in precise amounts. The production process involves forming this composition into a sheet at a controlled chill-roll temperature and subsequently annealing it at specified conditions. This innovation provides a robust solution for packaging in various applications.
His second patent focuses on thermoplastic resin sheets that exhibit minimal thermal shrinkage, within ±0.3%. The production process for these sheets entails co-extruding two types of thermoplastic resins, where the second resin is nonadhesive to the first, creating a unique sheet-like structure. This method results in sheets with low mechanical strain and reduced optical anisotropy, making them ideal for use in liquid crystal displays (LCDs) and other optical devices.
