| The most common are known as polyester, vinyl ester, epoxy, phenolic, polyimide, polyamide, polypropylene, PEEK, and others. |
| Polyimide film has been widely used as an insulator in electronics due to its flexibility, excellent insulation, and heat resistance. |
| An example of this type of adhesive is polyimide that is formed by the polymerization reaction of an aromatic amine with an aromatic anhydride. |
| It is used almost exclusively in conjunction with polyimide film as the dielectric. |
| During the cyclisation of the intermediate polyamic acid to the polyimide, the resin becomes less hydrophobic. |
| Materials such as polyimide are prone to low copper adhesion. |
