Latest Patents
One of his latest patents is for a polyarylene sulfide resin particulate. This innovative material has a mean particle diameter ranging from more than 1 µm to 100 µm, with a uniformity coefficient of 4 or less. The melt viscosity at a temperature of 300°C and a shear rate of 1216 sec is between 150 to 500 Pa·s. Additionally, the recrystallization temperature is defined as the temperature of the heat generation peak during crystallization when cooled from 340°C to 50°C at a rate of 20°C/min, which ranges from 150 to 210°C. This polyarylene sulfide resin particulate is particularly suitable as a material powder for producing three-dimensional moldings through powder sintering in 3D printers.
Another notable patent involves a method for producing polybutylene terephthalate resin shaped moldings. This method includes supplying a 3D printer with a polybutylene terephthalate resin powder mixture. The mixture contains 100 parts by weight of a polybutylene terephthalate resin powder material with a mean diameter of more than 1 µm and 100 µm or less, a uniformity coefficient of 4 or less, and a terminal carboxyl group quantity of 35 eq/t or more and 50 eq/t or less. It also includes 0.1 to 5 parts by weight of inorganic particles with a mean diameter of 20 to 500 nm.
