Product Description

Product Description

 

Polyimide film is condensed with 4-formic acid-2-anhydride of benzene and 4.4 -diamino-biphenyl-ether oxide. It has high low-temp resistance, radiation hardening and good Dielectric. Film surface is smooth, clean without any crease, bubble and impurity. Film is offered on roll or coil, Width 10-1000mm is utilized for compound rolled conducting wire, each roll is not less than 300m, if for the other electronic engineering material, each roll is not less than 50m. According to the customers request, the Pellicle also can be banding.
