摘要： A molded body which is formed from a shaping material containing a fluororesin powder. The fluororesin powder has a D50 of 30 µm or more and 200 µm or less and a D10 of 12 µm or more. Also disclosed is a method for forming a molded body from a shaping material containing the fluororesin powder, the method including controlling the temperature of the fluororesin powder; and irradiating the fluororesin powder with a laser at the controlled temperature to fuse the same.

摘要： A thermoplastic resin pellet is columnar. A cross-sectional shape taken along a plane orthogonal to a height direction of the thermoplastic resin pellet has a longer diameter represented by “a” and a shorter diameter represented by “b”. A ratio a/b is greater than or equal to 1.0, and the ratio a/b is less than or equal to 2.6. A ratio α of a unit height volume of a cylindrical portion of a hopper of a molding machine, into which the thermoplastic resin pellet is loaded, to a volume of the thermoplastic resin pellet is greater than 16. A method for manufacturing an electric cable includes supplying the thermoplastic resin pellet to the hopper, melting the thermoplastic resin pellet in the cylinder to supply molten resin to the die, and extruding the molten resin from the die to form a sheath on a core wire.

摘要： Provided is a method for producing a purified fluoropolymer containing less fluoridable end groups. The production method includes: (a) melting a fluoropolymer to give a molten fluoropolymer; (b) reducing a reaction inhibitor in the molten fluoropolymer; (c) bringing the molten fluoropolymer into contact with an active substance after the step (b); and (d) removing a volatile matter from the molten fluoropolymer after the step (c).
