An insulated electric conductor includes a flat or round wire made of one or more electrically conductive materials, the flat or round wire having an exterior surface that is free of an oxide layer; and an insulating layer adhering directly to the oxide-layer-free exterior surface to form a coating around the oxide-layer-free exterior surface, the insulating layer being made of at least one thermoplastic material which provides electrical insulation. The flat or round wire is designed to conduct an electrical current.

The invention relates to an insulated conductor comprising an elongate conductor provided with an insulating layer which comprises a polymeric material. Said polymeric material has a crystallinity of at least 25% and includes a repeat unit of general formula

wherein t1 and w1 independently represent 0 or 1 and v1 represents 0, 1 or 2. The insulating layer has a thickness in the range 2 μm-300 μm.

A cable includes: core wires comprising a pair of inner conductors and an inner insulating layer separately covered around each of the pair of inner conductors; a wrapping layer covering the core wires; a shielding layer covering the wrapping layer; and an outer coating layer covering the shielding layer; wherein the wrapping layer comprises a first wrapping layer covering the core wires and a second wrapping layer covering the first wrapping layer.

A cable includes an inner conductor and a dielectric layer extending around the inner conductor. The dielectric layer includes a linearly-stretched polypropylene film having a porous structure that includes a plurality of pores that extend through a thickness of the linearly-stretched polypropylene film. The dielectric layer includes air molecules trapped within the pores of the linearly-stretched polypropylene film such that the dielectric layer includes polypropylene and air. The cable includes an outer conductor extending around the dielectric layer.

A resin composition contains propylene, ethylene, and styrene, and has a melting point of 140° C. or more and 150° C. or less, and the enthalpy of fusion of the resin composition is 55 J/g or more and 90 J/g or less.

The present disclosure relates to a UV- and heat-curable ladder-like polysilsesquioxane copolymer and a method for preparing the same. Since a controlled functionality can be provided only on a desired region via a thiol-ene click reaction without an additional additive, an insulating layer having a low dielectric constant and a microcircuit pattern can be formed without an additional etching process.

Magnet wire included extruded insulation formed from a blend of two or more different polymeric materials is described. A magnet wire may include a conductor and insulation formed around the conductor. The insulation may include at least one layer of extruded insulation formed from a blend of a first polymeric material and a second polymeric material different than the first polymeric material. The first polymeric material may include one of polyetheretherketone, polyaryletherketone, polyetherketoneketone, polyphenylsulfone, polyphenylene sulfide, or polybenzimidazole. The second polymeric material may include one of polyphenylsulfone, polyetherimide, polyethersulfone, polyphenylene sulfide, polycarbonate, or polyester.

Logic mechanisms operate to define the position of at least one mechanical output based on the position of at least one mechanical input. Some mechanisms are configured to determine, based on the input position(s), whether a path to transmit motion to an output exists or does not exist. Some mechanisms are configured to determine, based on the input position(s), whether or not motion of a driven element can be accommodated without moving an output. Some mechanisms are configured to determine, based on the input position(s), whether or not one or more elements are constrained to transmit motion to an output.

Disclosed herein is a styrenic block copolymer [A1-B1-C1], consisting essentially of polymer blocks A1, B1 and C1. A1 is a poly(para-alkylstyrene) block having a molecular weight from 1,000 to 60,000 g/mol. B1 is a hydrogenated polyisoprene block or a hydrogenated polybutadiene block having a molecular weight from 1,000 to 100,000 g/mol. C1 is a polystyrene block having a molecular weight from 1,000 to 100,000 g/mol; or a polymer block consisting essentially of polymerized styrene units, and hydrogenated butadiene and/or isoprene units, and having a molecular weight from 1,000 to 100,000 g/mol. Prior to hydrogenation, the block B1 has a vinyl content of 5-75 mol %; and the block C1 forms 1-80 wt % of the overall weight of the block copolymer. The selectively sulfonated forms of the copolymers are useful as high dielectric materials.

A polymeric composition includes an ethylene polymer, 0.05 wt % to 0.25 wt % carbon black based on a total weight of the polymeric composition and a polymeric ultraviolet light stabilizer including a hindered amine moiety and having a weight average molecular weight from 5,000 g/mol to 20,000 g/mol as measured according to Gel Permeation Chromatography.
