Brief introduction of polyimide film

The preparation method of the film is that: the polyamic acid solution is cast into a film, and after the stretching, the film is imidized at a high temperature. The film is yellow and transparent, a prominent high temperature, radiation resistance, chemical resistance and electrical insulation properties, long-term use in the air 280? or so.

 

Chemical properties of polyimide membrane

Polyimide film is high temperature resistant, chemically stable, fire retarding,. Typical polyimides are anti-chemical solvents such as hydrocarbons, esters, ethers, alcohols and chlorofluoroalkanes. They are also resistant to weak acids but are not recommended for use in more concentrated alkaline and inorganic acids environments
