Polyimide

        Polyimide (PI) refers to a class of organic polymers in which the repeating structural units of the polymer contain imide groups. Its main preparation method is to prepare the precursor of polyimide, namely polyamide acid (PAA), through the amidation reaction of dianhydride and diamine, and then prepare polyimide through thermal imidization reaction. Thanks to its unique chemical structure, polyimide has excellent comprehensive properties and is known as a "problem-solving expert". It has excellent resistance to high and low temperatures, good electrical insulation, mechanical properties, chemical stability, corrosion resistance, radiation resistance, dielectric properties, dimensional stability, and more.

Polyimide film is mainly applied in the following fields:

Electrical insulation, electronic manufacturing substrates, new energy, 5G communication, etc
