DPE | 4,4′-Diaminodiphenyl Ether | ODA | 4,4′-Oxydianiline

4,4′-Diaminodiphenyl Ether (DPE), also known as 4,4′-Oxydianiline (ODA), is primarily used as a monomer to produce high-temperature resistant polyimide and poly(ester)imide resins. It is essential in manufacturing insulating varnishes, wire enamels, flexible printed circuits, aerospace composites, adhesives, and flame-retardant fibers.
