H Type Polyimide film
|
H 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℉)
and as high as +260℃(+492℉).
