Benefits of technology

[0006] There exists a need in the magnet wire art for high performance insulation coatings that exhibit robust electrical insulation, long term thermal aging stability, and environmental resistance. There exists a need in the magnet wire art to economically produce high performance magnet wire insulation coatings, by reducing the amount of expensive resins used in the insulation coating. Further, there exists a need in the magnet wire art to produce high performance insulation coatings containing minimal amounts of consumable performance and stability additives. In addition, there exists a need in the magnet wire art to be able to economically and reliably insulate the wire by extrusion coating, solvent coating, film wrapping or powder coating.

Problems solved by technology

Polyphenylsulfone is an expensive resin due to the high cost of biphenol.

Abstract

A magnet wire containing a melt processable, thermoplastic resin blend insulative coating developed for use in high temperature electrical insulation systems. The invention relates to a high temperature electrical insulation containing a sulfone polymer blend for particular use with magnet wire. The sulfone polymer blend contains two poly(aryl ether sulfones), such as polyphenylsulfone and polysulfone.

Description

[0001] This application claims the benefit of U.S. Provisional Application No. 60 / 389,484, filed on Jun. 19, 2002.FIELD OF THE INVENTION [0002] This invention relates to a magnet wire comprising a melt processable, thermoplastic resin blend insulative coating developed especially for use in high temperature electrical insulation systems. More particularly, this invention relates to a high temperature electrical insulation system containing sulfone polymers for use with magnet wire and wherein the sulfone polymers comprise a blend of two poly(aryl ether sulfones). The blend exhibits improved electrical insulation and long term thermal and environmental aging stability relative to polysulfone. BACKGROUND OF THE INVENTION [0003] Polymeric materials are used in magnet wire insulation coatings. Although thermoset materials are commonly used, magnet wire insulation coatings can include thermoplastics. These polymeric materials are applied as extruded coatings, wrapped films, powder coatin...
