Kapton film is a brand name for Polyimide, which is a product of Dupont. It is a non-thermoplastic polyimide film.

It has a dark yellow colour and has a high working temperature. The temperature range  is -260C to +400c. This makes the film versatile.

Kapton film does not have a melting point and has a low coefficient of linear expansion value. This would typically be 20 parts per mm / C. This is based on test valued of -14 to +38C.

The film is not heat sealable.  Specially prepared surfaces can be bonded to it.

 Kapton has been specified for components used in space exploration. Other applications include pressure-sensitive tape and fibre optic cables.

Other uses include automotive diaphragm sensors and manifolds. Additionally, it can be used as a nonstick heat barrier for the production of PTFE belts.

These belts require hot platens that be able to thermally bond two layer of PTFE coated glass cloth together. Kapton is ideal to use as a barrier between the hot aluminium platen and the PTFE as it protects PTFE from damage.

Polyimide is made by casting . The casting process involves pouring semi-liquid onto a shiny surface and then curing it. When cured, the thin layer (film) is peeled off and batched onto a roll.

It is possible to make self adhesive tapes from the film by preparing a surface with a chemical etch.

The adhesive is applied by bonding to the etched surface.
