Is polyimide film less resistant to high temperature and low temperature?

Polyimide film is a new type of high temperature resistant organic polymer film, which is composed of pyromellitic dianhydride (PMDA) and diaminodiphenyl ether (ODA) in a very strong solvent dimethylacetamide (DMAC) Medium condensation and salivation are formed, and then imidization is carried out. It is the most functional thin-film insulating material in the world and has excellent strength. Electrical function, chemical stability and high radiation resistance, high temperature and low temperature resistance (-269~ +400~C).
