Widely Used Polyimide Pi Film with Excellent Properties
Application/Model
Our products apply to national defense industry aerospace industry, electric motor industry, FPC and TAB of electronic industry, Grade H, C insulating materials (pulling motor, submersible oil electric motor , nuclear power equipments, high-temperature-resistant materials, special electric appliances, fire-proofing bus duct, gas mask, loudspeaker voice skeleton), our products polyimide films as parent metal is the best choice of FPC, PST, flexible copper layer plate, LED and high-temperature insulated materials.
Welcome to consult.
H Polyimide film is a common polyimide film condensed with 4- formic acid-2- anhydride of benzene, and 4.4-diamino-biphenyl-ether oxide. This product has excellent mechanical capability, favorable electric insulation at temperature from -269ºC to +260ºC. It can be used in compound insulation material, adhesive tape, electric wire and motor industry, etc.
Package&Storage: Packed in rolls and in carton; store at room temperature; avoid fire. The storage period is 12 months.
