Chemical properties of polyimide film

Polyimide is chemically stable. Polyimide does not need to add flame retardant to prevent burning. General polyimides are resistant to chemical solvents such as hydrocarbons, esters, ethers, alcohols and chlorofluorocarbons. They are also resistant to weak acids but are not recommended for use in strong alkali and inorganic acid environments. Certain polyimides such as CP1 and CORIN XLS are soluble in solvents. This property helps to develop their applications in spray coating and low temperature crosslinking.
