New application for PolyImide
Thought it would be useful to cite another application of polyimide resin.
An additional use of polyimide resin is an an insulating layer in the Cite error: There are <ref> tags on this page without content in them (see the help page).manufacture of digital isolator semiconductor chips. The polyimide layers have good mechanical elongation and tensile strength, which also helps the adhesion between the polyimide layers or between polyimide layer and deposited metal layer, (see figure). The minimum interaction between the gold film and the polyimide film, coupled with high temperature stability of the polyimide film, results in a system that provides reliable insulation when subjected to various types of environmental stresses.

- This will be data for just one particular polyimide (which one?) and isn't appropriate content anyway for an article about a class of polymers. -- Ed (Edgar181) 17:09, 7 April 2014 (UTC)
intro paragraph missing image
the intro paragraph says "The structure of imide is as shown" but the page has no images at all. — Preceding unsigned comment added by Nmz787 (talk • contribs) 20:30, 18 July 2014 (UTC)
