There are provided a process for producing an electrical wire molded body comprising: step I of melting and kneading a polyethylene-based resin (a), a polypropylene-based resin (b), a block copolymer (c) of an aromatic vinyl-based compound and a conjugated diene-based compound and the like, and a silane coupling agent (g), and other components, to produce a silane crosslinkable flame retardant polyolefin (A); step II of melting and kneading a polymer selected from the components (a) to (c) and a silanol condensation catalyst (i), to produce a silanol catalyst rein composition (B); and step III of mixing the components (A) and (B), melt molding the mixture on a conductor and then crosslinking the molded body in the presence of water.

A method of pretinning a guidewire core made of shape memory alloy and having an elongate axis, comprising: placing a ball of solder in a pocket in a soldering block; melting the ball of solder; holding a guidewire core over the ball of solder; lowering the guidewire core into the ball of solder; removing the guidewire from the ball of solder.

The disclosed medical device has high visibility on non-woven fabric having a color such as green, blue, or the like, excellent identifiability from other medical devices having a color such as green, blue, or the like, and high surface smoothness. The medical device comprises an elongated body and a resin layer for covering at least a proximal portion of the elongated body, in which the resin layer has a first layer which includes a first fluororesin, titanium oxide, and a dispersant, and a second layer which is formed on the first layer and includes a second fluororesin. The content of the titanium oxide is 30% by weight or more relative to the solid content of the first layer, and an acid value of the dispersant is 20 to 90 mg/KOH.

In manufacturing a pleated stretchable composite member, a first sheet-like nonwoven fabric and a stretched cord-like elastic member (rubber thread, etc.) are positioned on the protruding surface side of a pattern roll, and a hot melt adhesive is intermittently applied to the stretched cord-like elastic member and the first sheet-like nonwoven fabric at locations where the protruding surface of the pattern roll is present, and then the stretched cord-like elastic member and the first sheet-like nonwoven fabric intermittently coated with the adhesive and a second sheet-like nonwoven fabric are integrally adhesively fixed at positions corresponding to locations where the protruding surface of the pattern roll is present. In the stretchable composite member, the valleys of the upward-facing breathers of the top-layer nonwoven sheet and the valleys of the downward-facing breathers of the bottom-layer nonwoven sheet are adhesively fixed via a stretchable elastic members (rubber threads) between the two nonwoven fabric sheets.

One aspect is a method for producing a plurality of wire elements, including providing a metal wire, coating the metal wire with a first layer to obtain a first coated wire, subjecting the first coated wire to a first quality control process, marking any first defects identified in the first quality control process, coating the first coated wire with a further layer to obtain a further coated wire, and cutting the further coated wire to obtain a plurality of wire elements. Prior to cutting the further coated wire to obtain the plurality of wire elements, a first length of the first coated wire is less than 10% longer than a further length of the further coated wire.
