Specific Applications Of Polyimide Tape

By Cathy Mercer


When referring to a polyimide tape, someone is referring to an ultra thin tape used as a cover. It can withstand very high temperatures, something which makes it very famous among many fields. Their ability to do this makes them suitable in the occasion of a fire where they are used to cover the surface. The aviation industry likes it because of its light weight. It is the most suitable since all the materials that are usually used in this industry are preferably very light.

There are different molecules that are involved in their manufacture. Some very complex procedures as step polymerisation are the ones that are used to synthesise the polyimide tape. Dianhydride is the main compound that is also used in this process of synthesis in the procedure named above. This whole process takes place in very high temperatures of up to 573K.

This adhesive comes with different uses in different fields. A field that is very familiar with these tapes is the aviation field. Aircrafts use it because it has very good insulation properties. The civil aircrafts as well as the military ones both depend on it for their wiring. The main reason given for this is its weight which is relatively lower than that of other insulators. It has high insulation power and is able to condone very high ranges of temperature.

Space crafts are the other instruments that really require them in their functioning. The garments of the astronauts themselves also have a layer of this vital adhesive. The space crafts require them mainly for thermal insulation. The famous Solar Sails can use them as plastic support insulators. The reason for this is that they help in the long term space environment.

They are also used in the medical field. The sources of x-rays need them to act as their covers. It also transmits these x-ray waves very fast. This is why they are usually used in this field. Their mechanical and thermal stability makes them fit for this field too.

Finally, they are used for 3D printing. This is because of its adherence to ABS plastic. Its main role is to cover the surfaces of the platform that is heated. The other role that it plays is that of a print bed material. This whole process is usually carried out in a RepRap 3D printer.

The adhesive also has some disadvantages linked to it. Short circuits from their wiring is the main disadvantage. The aircrafts and space crafts are the ones that experience it the most since they are the ones that do their wiring using polyimide. They, therefore, have to embark on the repairs. Sometimes it is very bad that they have to do the wiring all over again.

In conclusion, these polyimide tape is usually available in three dimensions in terms of thickness. There are 1,2, and 5Mil thick tapes that are available in the market. One gets to choose from this list, the one that is most suitable for whatever function they want it to perform. They are usually also packaged in rolls.
