Latest Patents

Umemoto holds a patent for a method titled "Continuous preparation of shaped long articles of polyimide." This patent describes a process for continuously forming a shaped long article from an aromatic polyimide powder. The method involves supplying a powdery mixture containing an aromatic polyimide powder with a heat loss ratio of not more than 2 wt. % and a mean particle size ranging from 0.1 to 40 micrometers. Additionally, a small amount of fluororesin powder is included in the mixture. The process is carried out in a ram-extrusion apparatus at temperatures not lower than 300 degrees Celsius, filling the mold and ram-extruding the mixture at pressures between 100-1,500 kg/cm². The resulting extruded long article exhibits a specific gravity of more than 1.380, a radial crushing strength of not less than 800 kg/cm², and a coefficient of linear expansion in the radial direction that is less than that in the longitudinal direction. He has 1 patent to his name.
