Abstract: 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.

Abstract: 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.

Abstract: A catalytic process and a nano material for the conversion of moist carbon dioxide into methanol, propyne and oxygen have been developed. In the process invented, hydrogen is produced from water in a catalytic reaction, when the moist carbon dioxide enters into the catalytic reactor, resulting in C—O and H—OH bond breakage at a relatively low temperature and at atmospheric pressure in a single step using a combination of catalytic materials comprising at least three metals dispersed on a catalyst support, preferably anatase form of titanium dioxide, to induce a multifunctional surface chemical reaction for the production of oxygenated products such as hydrocarbons of different chain lengths.
