Polyimide Film (similar to Kapton HN)
|
|
|
Properties |
|
Polyimide film
(similar to Kapton HN) is achieved by polycondensation of PMDA
and ODA in strong polar solvents and through the process of
forming film and imine treatment at high temperature, which
possesses excellent physical, chemical, and electrical
properties, atomic radiation resistant, solvent resistant, low &
high temperature resistant, It performs successfully in the wide
range of temperature as low as -452F(-269c) and as high as
+500F(+260c). Because of its unique excellent properties, it is
the most ideal choice in many applications. |
