China and India are the leading exporters of 4,4'-Oxydianiline (CAS 101-80-4), accounting for the majority of global shipments, while the United States, Germany, and South Korea represent the largest importers. These importing nations consistently absorb significant volumes, reflecting sustained industrial demand—particularly in polyimide and epoxy resin manufacturing. Recent trade data indicate relative stability in export volumes from Asia, though fluctuations in 4,4'-Oxydianiline prices have accompanied supply-chain recalibrations among key European and North American buyers.
4,4'-Oxydianiline is a white to pale yellow crystalline solid at room temperature, with a melting point of approximately 187–190 °C and low volatility. It is an aromatic diamine and classified as an organic chemical intermediate. Its primary industrial use is as a monomer in the synthesis of high-performance polyimides and polyamide-imides, where it imparts thermal stability and mechanical strength. It is also employed in the production of specialty epoxy curing agents and certain azo dyes. Typical application areas include aerospace composites, flexible printed circuit boards, high-temperature coatings, and advanced electrical insulation materials.
Bis(p-aminophenyl) Ether is a reagent used in the preparation of polyimide-silica composite membranes for gas separation techniques. In addition, it is used in the synthesis of polymer films for electrolyte membranes. Dyes and metabolites, Environmental Testing
