four different types of kapton polyimide film

Polyimide Film

Polyimide film, such as Kapton, has a unique combination of electrical, thermal, chemical, and mechanical properties that withstand extreme temperature, vibration and other demanding environments. It does not melt or burn, as it has the highest UL-94 flammability rating: V-0. Our films come in a variety of thickness, ranging from 0.5 mil to 20 mil. Normally it is a transparent amber colour, but can also be pigmented for color. In addition, other grades of film are available with the following attributes heat sealable, thermo conductive, corona resistant, anti static, metalized.

How is polyimide film made?

It is synthesized by polymerizing PMDA and ODA. This innovative construction allows the film to boast several performance features. Including excellent physical properties and high temperature resistance. The film also provides excellent chemical resistance, as there are no known organic solvents for the film. High dialectic strength is another impressive quality, with an astonishing 6000V/mil for just 1 mil of film. Thus, makes it an ideal insulating material for use with high voltage.

Kapton Film vs Polyimide Film

Essentially, the only difference lies in the name. Polyimide is the chemical name of the  film, and Kapton is the trade name of the same polymer. If you are looking for high performance Kapton film, with an excellent combination of electrical, thermal, chemical, and mechanical resistances, look no further than our film. They are UL listed and meets both Mil and ASTM specifications.

What is polyimide film used for?

It has excellent thermal properties, with a temperature range of -269°C to 400°C (-450°F to 752°F). Making the film uniquely suitable for many high temperature applications.

Aerospace

Engineers have been using polyimide insulated electrical wiring for a long time in civil and military aircraft. The film’s lightweight construction provides a desired advantage over other insulators. Aluminum polyimide film can be converted and layered together to make multi-layer insulation.

Automotive

FEP Polyimide film can be die cut to shape, ideal for switches, diaphragms, and sensors.

Electronics manufacturing

Due to its electrical insulation ability and temperature stability, polyimide film is the optimal substrate for many high temperature applications in electronics industry.

Insulation

Polyimide materials are lightweight, flexible, resistant to heat and chemicals. Therefore, making them an excellent choice as an insulating film for cables and magnet wires.
