The present invention relates to a continuous process for the production of polyol modified polyalkenylene terephthalates and the application of such polyol modified polyalkylene therephtalate on wire enamels.

A method for forming magnet wire includes co-extruding multiple layers of different insulating materials. A conductor may be provided, and extruded insulation may be formed around the conductor by co-extruding both a first layer of thermoplastic insulation and a second layer of thermoplastic insulation with the second layer formed around the first layer. The first layer may include a first polymeric material having a first thermal index, and the second layer may include a second polymeric material having a second thermal index higher than the first thermal index.

A flexible flat cable includes a low-dielectric adhesive layer, a plurality of conductors, two shielding layers and two insulating protective layers. These conductors are located inside the low-dielectric adhesive layer and are spaced apart. The two shielding layers are laminated individually to the upper and lower surfaces of the low-dielectric adhesive layer. The two insulating protective layers are laminated individually to the two shielding layers.

The invention provides a copolyetherester compositions that are resistant to burning and which show reduced smoke production when exposed to heat or flame.

The present invention relates to the use of a linear octafluorobutene as a dielectric compound in an environmentally safe dielectric-insulation or arc-extinction fluid for an apparatus for the generation, the transmission, the distribution and/or the usage of electrical energy.

An insulated wire comprising a conductor and a bubble-containing insulating layer, directly or indirectly coating the outer periphery of the conductor and containing a thermosetting resin, wherein the bubbles in the bubble-containing insulating layer include flattened bubbles whose oblateness in the cross-section perpendicular to the longitudinal direction of the insulated wire (lateral length of the bubble cross-sectional shape/vertical length of the bubble cross-sectional shape) is 1.5 or more and 5.0 or less.

Thermoplastic molding compositions containing A) from 29 to 99.99% by weight of a polyester, B) from 0.01 to 10% by weight of an ionomer composed of at least one copolymer of B.sub.1) from 30 to 99.9% by weight of ethylene B.sub.2) from 0 to 60% by weight of 1-octene or 1-butene or propylene or a mixture of these and B.sub.3) from 0.01 to 70% by weight of functional monomers, where the functional monomers are selected from the group of the carboxylic acid groups, carboxylic anhydride groups, carboxylic ester groups and mixtures of these, where component B) has been neutralized to an extent of at least 20% with alkali metal ions, based on 100% by weight of A) and B), and C) from 0 to 70% by weight of other additional substances, where the sum of the % by weight values for A) to C) is 100%, for use in the production of cable sheathing or optical-conductor sheathing via blow molding, profile extrusion, and/or pipe extrusion.

Magnet wire with flexible corona resistant enamel insulation may include a conductor and a multi-layer insulation system formed around the conductor. The insulation system may include a basecoat formed from first polymeric enamel insulation, a midcoat formed from second polymeric enamel insulation, and a topcoat formed from third polymeric enamel insulation. The midcoat may include a filler containing silica dioxide and chromium oxide dispersed in a base polyamideimide material. Additionally, the magnet wire may exhibit few or no cracks in the topcoat when the wire is bent 180 degrees around a 4 mm mandrel.

A composition, method, and system for directly printing and creating complete functional 3D electronic circuits and devices without any thermal or laser post-processing treatment, by using at least Triphenylamine (TPA) as a powder binding agent. The composition can have mechanical characteristics that allow it to be melted and extruded on a structure, and electrical properties that allow it to function as at least one of a conductor, insulator, resistor, p-type semiconductor, n-type semiconductor, or capacitor.
