Application Uses Of Polyimide Tape

By Cathy Mercer


This is usually a very thin film that mostly is used as a cover. It is also well known for its property of withstanding extremely high temperatures. This is also the reason why it is used to cover burning houses. It is also very light something which has led to it being preferred in the aviation industry. Clearly the aviation industry goes for the lightest materials even to make the place crafts themselves, therefore polyimide tape fits in too.

Their manufacture involves then usage of different molecules. Their synthesis of this polyimide tape is done using a very complex procedure by the name step polymerisation. The process named above also involves the use of a compound called Dianhydride so as to have a successful synthesis. Very high temperatures of up to 573K are involve in this whole procedure.

This tape has several some vital roles that it plays in different fields. One of the fields is aviation and in this case, aircrafts. Both the civil and military aircrafts are beneficiaries as they sue its insulated wiring. Its insulation power is very high. It can also be able to tolerate extremely high temperatures. With all these properties in one tape, who could hesitate to try and use them in this industry?

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.

This tape however has some disadvantages. One of them is that their wiring causes very many short circuits. This is mainly experienced in the aircrafts and space crafts that use its wiring. The short circuits cause some sparks. This causes so many repairs to be done on them. Sometimes it goes to a point where they are forced to just do a whole re-wiring procedure.

There are only three types of polyimide tape considering their thickness. They can be found in 1,2 and 5 Mil dimensions only. It is upon the person that needs them to get one of the best size that will serve them to best ability that they expect them to. Their packaging is in the form of rolls mostly.
