Kapton tape is a strong and durable tape with the ability to bond even very thin sheets of thin film material, called plies. It is used in a variety of applications, including packaging tapes, tape dispensers, label protection tapes and protective coatings for various materials. Kapton tapes are available in rolls of different thicknesses and sizes, depending on the application. 

There are two basic types of Kapton tape; thermal and plastic. 

  • The thermal type is generally thicker and is generally used for more delicate applications, as it can melt very quickly under the right conditions. 
  • However, the plastic type can be used for all applications and it provides a good bond even with different types of backing paper.

What is Kapton Tape Made From?

Kapton tape is made from polyimide tape with silicone adhesive. The adhesive is thermo-sensitive, which means that heat can melt and extend the life of the tape. This is why Kapton tape is also commonly used for packaging purposes, particularly in food service and distribution. Kapton tapes are typically sold as 30 meter rolls or thicker, with interlocking tabs. Kapton tape is heat resistant up to 300 degree Celsius and it can resist electrical and chemical interference. They are also effective for bonding and cutting, and some types can also be used as electrical insulators.

Static and Chemical resistance

Kapton tape is an adhesive that has the added benefit of having very high static and chemical resistance. This means that when the tape is adhered to a surface, the surface is not subject to abrasion, which increases the life of the material being bonded. Some other types of adhesives with high static and chemical resistance have been designed specifically for use with Kapton tape.

Seat Heaters

Kapton tape for seat heaters is a relatively new product, but it is finding a growing number of takers. In addition to its excellent thermal performance, kapton tape for seat heaters features other advantages. For example, because the kapton tape used in seat heaters is flexible and thick, it can be used to cover a much wider temperature range than most other forms of insulation. Moreover, because polyimide tape is also heat resistant, your seats will stay warm even in the middle of the coldest winter.

Commercial Applications

  • Kapton tape is also commonly used in industrial and commercial applications, particularly in the manufacturing of insulation. Its ability to maintain its integrity and flexibility even under harsh conditions makes it highly suitable for use in those situations. Kapton tape for insulation is especially popular because it has the additional advantage of providing superior heat resistance. Insulation is especially important in the manufacture of tires and various other goods. One problem that many people face with fiberglass insulation is that it becomes brittle and can be easily punctured. By using kapton tape for seat heaters, you can help avoid this problem because the tape’s high heat resistance makes it very difficult for metal objects to puncture it.
  • The kapton tape for insulation that is sold in stores is usually a little bit thin, and may have some air bubbles or holes. Air bubbles and holes in the tape are the reason why it is not as flexible as standard fiberglass insulation, but it does provide excellent heat resistance. To make the kapton tape as thin as possible, manufacturers simply cut it with diamond blades. Although cutting it by hand is not difficult, it is not advisable to do so because the edges may become blunt and distorted.
  • Kapton tape for seats and other areas is available in rolls of different sizes, depending on the required application. It is important to note that one roll of kapton tape will not be able to handle the required temperatures of different applications. This is why it is important to buy kapton tape that is specially made for a certain application. It should also be ensured that the tape is already pre-wrap if it is to be used for electrical insulating purposes.
  • Kapton tape that is made out of silicone adhesive will be able to withstand high temperatures up to 500 degrees Fahrenheit. However, it is important to note that the adhesive itself is only about one mil thick, and is able to stretch to two millimeters when heated. Therefore, although the kapton tape can handle high temperatures, it will not be able to handle the temperatures which can occur when the material is exposed to direct flames. Therefore, if you are going to use kapton tape for electronics, make sure that you place them in a fireproof box. Otherwise, they will melt.
