Product Description:Polyimide film is made up of both pyro mellitic di-anhydride(PMDA) and 2 amino diphenyl ether (DDE) approved by polycondensation and stretch film again the imminent strong polar solvent .Polyimide film has excellent high and low temperature resistance, electrical insulation resistance,caking property, radiation resistance and medium resistance.Use for a long time in the temperature range of -269 ~ 260 . It was called “golden film” and have excellent performance.
Application:ts was widely used in space technology, F and H motor, the insulation of the electric equipment such as transformers, FPC (flexible printed circuit board), TAB (pressure sensitive adhesive tape only), spaceflight, aviation, computer, the electronic components industry,automobile, transportation,atomic energy industry and high-grade household electrical appliance set. Its the indispensable materials in modern industry.
