Application of ODA
As a special engineering material, polyimide has the advantages of high temperature resistance, radiation resistance and high mechanical strength. It is used in film, coating, fiber, aerospace, electronic and electrical industry, foam plastic and photoresist, etc. ODA（4,4'-Oxydianiline） is one of the main ingredients. At the same time, ODA（4,4'-Oxydianiline） can also be used in the production of crosslinking agents, and widely used to replace the carcinogenic benzidine in the production of azo dyes and reactive dyes. Therefore,ODA（4,4'-Oxydianiline） is intermediate with high added value.
