4,4'-Oxydianiline: A key raw material for polyimide resins
4,4'-Diaminodiphenyl ether (ODA) is a core intermediate for polyimide resins. The ether bonds and amino groups in its molecular structure impart excellent thermal stability and mechanical strength to the material. Polyimide resins synthesized using ODA can withstand temperatures exceeding 300°C and are widely used in aerospace, electronic packaging, and other fields.

4,4'-Diaminodiphenyl Polyimide Resin Ether FAQs
Q1: What role does ODA play in polyimide resin?
A: As a diamine monomer, it reacts with dianhydride to form an imide ring, which imparts high-temperature resistance and high insulation properties to the material.
Q2: How do we ensure safe transportation?
A: We use double-layer moisture-proof packaging and light-proof transportation to meet export sea transportation standards.
