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.

HN Polyimide Film

Polyimide film is synthesized by polymerizing an aromatic dianhydride and an aromatic diamine. It possesses a unique combination of properties, including excellent electrical and physical properties over a wide range of temperatures. It also has excellent chemical resistance; there are no known organic solvents for the film, and is self extinguishing with UL-94 V-0 rating. Making it an excellent choice for a variety of applications in many different industries, including wire and cable, coil insulation, substrates for flexible printed circuits, motor slot liners, magnet wire insulation, transformer and capacitor insulation.

Thermal Conductive Polyimide Film (MT)

CGS-7458 polyimide film series is enhanced with the thermal conductivity properties. This makes it ideal for use in dissipating and managing heat in electronic assemblies.

Corona Resistant (CR) Polyimide Film

CGS-7658 polyimide film was designed to withstand the damaging effects of “corona” which can cause ionization and eventual breakdown of an insulation material or system when the voltage stress reaches a critical level.

Aluminum (CM) Polyimide Film

CGS-7659 polyimide film formed by sputtering metal aluminum, which makes it conductive on one side and insulative on the other. It has excellence heat resistant, mechanical, chemical stability, radiation resistant.

Black (BL) Polyimide Film

CGS-7558 Black polyimide film exhibits an excellent balance of physical, chemical, and electrical properties over a wide temperature range. The homogeneous pigmentation provides better color integrity against flexural cracking or abrasion in comparison to black coatings or dyes.

ESD Polyimide Film

CGS-7758 Anti-static treated polyimide film offers outstanding thermal resistance and excellent electrical insulating properties. It is coated to result in low electrostatic discharge at unwind or removal.

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.
