High Quality 4,4′-Oxydianiline / 4,4′-Diaminodiphenyl Ether / ODA CAS 101-80-4

In the field of polyimides (PI), when copolymerized with pyromellitic dianhydride (PMDA), it yields polyimide films (such as the renowned Kapton film) that possess exceptional thermal stability, dielectric properties, and mechanical strength. These films are widely utilized in flexible printed circuits (FPC), copper-clad laminates (CCL), insulating tapes, and aerospace structural materials.

Furthermore, it is employed in the production of polyesterimides and polyetherimides. These materials are frequently processed into high-temperature-resistant enamels for magnet wire, insulating impregnating varnishes, and specialized composite materials, finding extensive application in the insulation protection of electric motors, transformers, and electronic components.

In the dye industry, 4,4′-diaminodiphenyl ether serves as a substitute for benzidine in the synthesis of azo dyes and reactive dyes. The dyes derived from this compound exhibit vivid colors, excellent fastness properties, and superior safety profiles, making them widely used in textile printing and dyeing applications.

Additionally, it can be utilized in the synthesis of curing agents for epoxy resins, chain extenders for polyurethanes, high-performance adhesives, and pharmaceutical intermediates, among other applications.
