A modular disk coextrusion die is formed of a plurality of cells stacked together. Each cell includes an arrangement of thin annular disks, including at least a first cap disk, a first distribution disk, a first transition disk and a first spreader disk. The modular disk coextrusion die includes at least one channel disk having at least one inlet opening and at least two outlet openings per inlet opening. The thin annular disks are configured so that a first of the outlet openings of the channel disk is in fluid communication with the first distribution disk in the first cell and a second of the outlet openings in the channel disk is in fluid communication with the first distribution disk in the second cell. The channel disk provides for a more efficient utilization of space at the inlet of the modular disk coextrusion die and enables the feeding of up to twenty melt streams.

A resin composition, containing an ethylene-vinyl acetate copolymer (A); and 15 to 30 mass parts of a bromine-based flame retardant (B), 5 to 15 mass parts of antimony trioxide (C), 6 to 12 mass parts of a benzimidazole-based aging retardant (D), 2 to 4 mass parts of a phenol-based aging retardant (E), 2 to 4 mass parts of a thioether-based aging retardant (F), 0.5 to 2 mass parts of a copper inhibitor (G), and 3 to 6 mass parts of a crosslinking aid (H), with respect to 90 to 100 mass parts of the ethylene-vinyl acetate copolymer (A); a vehicle wire harness; and, a method of producing a vehicle wire harness.

Systems and methods for forming insulation on magnet wire are provided. An extruder that includes one or more rotating screws may receive a thermoset polymeric material and process the thermoset polymeric material to increase its pressure and temperature. An extrusion crosshead assembly in fluid communication with the extruder may receive the thermoset polymeric material and press extrude the thermoset polymeric material as insulation onto a magnet wire. A curing device may then cure the extruded insulation material.

The invention provides an intermittent catheter comprising a hollow polymeric tubular body comprising a base polymer and a layer comprising a lubricious additive on or comprising a surface of the body, wherein the lubricious additive comprises an amphiphilic molecule.

An electrical wire includes a conductor and an insulating layer that covers the conductor and that is cross-linked. The insulating layer is a cross-linked product of a resin composition including (a) a base polymer containing polyolefin and a compatibilizer, (b) a photoradical generator of 0.5 parts by mass or more and 3 parts by mass or less relative to the 100 parts by mass of the base polymer, and (c) a reactive monomer of 1 part by mass or more and 5 parts by mass or less relative to the 100 parts by mass of the base polymer. A relative dielectric constant of the insulating layer is less than 2.5.

Disclosed are cable types, including a type THHN cable, the cable types having a reduced surface coefficient of friction, and the method of manufacture thereof, in which the central conductor core and insulating layer are surrounded by a material containing nylon or thermosetting resin. A silicone based pulling lubricant for said cable, or alternatively, erucamide or stearyl erucamide for small cable gauge wire, is incorporated, by alternate methods, with the resin material from which the outer sheath is extruded, and is effective to reduce the required pulling force between the formed cable and a conduit during installation.

A flexible tube production apparatus includes a die composed of: a cylindrical inner die having an outer face in which a groove is formed; a tubular member that is housed inside the inner die, and has a through-hole that allows a blade wire to be inserted from one end to the other end thereof; and an outer die that surrounds the inner die such that a predetermined gap is generated between itself and the outer face of the inner die, and has an extrusion hole that extrudes the resins having been supplied to the gap, onto the outer face of the blade wire that is fed from the other end of the tubular member. A resin supply portion supplies a first resin and a second resin to the die while the motor rotates the inner die about a center axis.
