Kapton Film for Electrical Insulation
The use of Kapton film in electrical insulation is among the most important uses of the film. The combination of its dielectric properties, flexibility and thermal stability makes it an ideal material for the insulation of wires, coils, motors, transformers, generators, and other electrical parts.
Conversion, lamination, punching and adhesive coating can also be done depending on the product type and specific requirements of the application. Some of the applications of Kapton film mentioned by DuPont include wire and cable tapes, formed coil insulation, flexible printed circuit substrates, motor slot liners, magnet wire insulation, transformer insulation and capacitor insulation.
For applications where insulation needs to be adhesive backed, customers can also consider Kapton tape and high-temperature insulation tapes.
Kapton Tape and Polyimide Tape
Kapton tape is an adhesive version of polyimide film that is used in applications where there is a need for heat-resistant electrical insulation and surface protection.
Decisions whether to use Kapton film or Kapton tape will depend on the applications. Usually, film is chosen where the polyimide should be laminated, wound or turned into an assembly, while tape is ideal in applications requiring adhesive insulation.
Harnawa manufactures polyimide tape, which includes Kapton tape as one of the high temperature insulation tapes.
Kapton Film Applications
The Kapton polyimide film is widely employed in many industries thanks to its excellent properties in thermal, electrical and mechanical fields.
Some of the applications include:
- Transformer and coil insulation
- Motor winding insulation
- Generator insulation
- Magnet wire insulation
- Cable and wire insulation
- Capacitor insulation
- Flexible printed circuits
- Electronic parts
- High temperature masking
- Electrical assemblies
- Automobiles’ electrical systems
- Industrial machines
- High performance electronics and aerospace
DuPont lists the following Kapton applications: electrical/electronic insulation, motor, transformer, capacitor, flexible printed circuit and wire/cable systems.
Where other types of insulation materials are needed for a different application, Harnawa provides high temperature aramid papers for the use in electrical insulation applications.
Kapton Film for Transformers, Motors and Generators
Kapton films find applications in electrical machines where the insulation needs to withstand the effects of heat, electrical stress, and mechanical stresses. It can be used for insulating coils, slot insulation, turn-to-turn insulation, and other electrical insulation applications.
Harnawa supplies industries that manufacture transformers, motors, and generators, along with high-temperature and electric vehicle applications.
Customers looking for complete insulation systems can also look at our fiberglass insulated cables for applications where flexible insulated wires are needed.
Kapton Film Price in India
Kapton film prices in India are influenced by a number of things such as DuPont grade, film thickness, roll size, quantity, availability and application requirements. There is therefore no set price for each Kapton film specification.
To give an exact quote, one must give details about the required thickness, width, quantity, grade and delivery location. Harnawa can quote prices based on the requirement.
Should you be evaluating various insulation products, the polyimide film range may be considered where a general polyimide insulation solution is required.
Kapton Alternative and Kapton Equivalent
The customer might be looking for an equivalent to Kapton or Kapton alternative film due to some considerations such as performance, availability, and cost. However, the choice will depend on several factors including the temperature range, dielectric properties, thickness, dimensional stability, mechanical strength and application.
One should not choose an equivalent to Kapton based solely on film thickness. In addition, the technical characteristics of a particular DuPont film and its application have to be analyzed before choosing an alternative product.
At Harnawa, we can advise on selecting polyimide film equivalents based on customer application requirements. We can also provide other insulation system solutions in cases when the customer requires different types of insulations.
