VC type 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,radiation hardening and good dielectric at temperatures as low as－269℃(－452.2°F) and as high as ＋260℃ (＋492°F). It is a special polyimide film
for Voice core.
