    4,4’-Oxydianiline

    4，4’-ODA

    4,4'-ODA is one of the two primary monomers (PMDA and ODA) for the synthesis of PI materials such as PI films, PI fibers, PI photosensitive materials, PI/PMI foams, PI adhesives, and PI-based composites. It is widely used in various fields such as flexible screens, rail transit, aerospace, fireproof materials, photoresists, electronic packaging, wind turbine blades, warships, and automobiles.
