Polyimide (PI) is a kind of polymer containing an imide ring (- co-n-co -) in the main chain, which is one of the best organic polymer materials.
Its high-temperature resistance is above 400 ° C, the long-term service temperature range is – 200 ~ 300 ° C, some parts have no obvious melting point, high insulation performance, the dielectric constant is 4.0 at 10 ^ 3 Hz, dielectric loss is only 0.004 ~ 0.007, belonging to class F to H insulation.
Polyimide film is a new type of high-temperature-resistant organic polymer film.
It is formed by polycondensation and casting of PMDA and ODA in a very strong solvent OMAC into a film, and then imidization.
Polyimide film is a key insulating material for electric and power appliances.
It is widely used in the manufacture of power transmission equipment, wind turbine equipment, variable frequency motors, high-speed traction motors, and high-voltage transformers.
FCCL is the main material of FPC widely used in the electronics industry, automobile industry, information industry， and various defense industries.
In this field, the polyimide film is mainly used as an insulating base film, and can also be used as FPC high-temperature tape.
