If you were to ask someone what they know about polyimide film there is a very good chance that they would be unable to tell you a great deal. This is surprising when you consider just how widespread this material is nowadays. This is a very useful material, largely thanks to the properties inherent with it. It is strong yet lightweight while at the same time it is flexible, its also heat and chemical resistant.
Modern electronics makes great use of this material due to some of these properties. For those still unconvinced, a prime example is the main cable of a laptop computer, the one which connects the body and the screen. Normal cabling would soon fail due to constant opening and closing of the laptop, so a more flexible solution was required.
If ever you see a laptop laid open, this flexible cable is very easy to spot. The metal tracks will be noticeable through an amber colored plastic sheet. It is this amber colored sheet that is the material in question.
Quite often the copper tracks will be sealed to the amber colored sheet by an adhesive. Due to the insulation qualities of this amber sheeting it is even possible for the copper tracks to be mounted on either side of the sheet. In such instances further insulation is required to prevent the outer faces of the copper tracks shorting against the casing. Also this sheeting can be utilized to mask printed circuit boards, and capacitors, transistors and similar devices can also be insulated.
However its the resistance to heat that is often the most important factor when industries decide to use this material. With this in mind manufacturers often elect to use this material in areas which have high operating temperatures. Out of interest this material will cope with temperatures in the region of 800F.
Normally when a material is subjected to such heat it will degrade. It would either begin to contract, or to stretch. Whichever scenario happens the material would no longer be fit for the purpose that it was originally intended. Fortunately this sheeting will survive these temperatures with no ill effects. The only noticeable difference will be that sheeting which is in use, and subject to high temperatures, will appear darker.
This material was first used in the defense industries and by the military. Since its entrance into the civilian world it has slowly become more and more common, as its range of applications has grown. This can occur anywhere between the space agencies and micro electronics.
Engines are a prime example, as they operate they become hot. Engines can be found throughout the vehicle industries, aviation industries and even space flight. The sheeting is highly resistant to heat, and so will not conduct heat from one side to the other. Therefore it is ideal if something needs to be protected from conducted heat, such as engine cables. If these cables were unprotected the normal insulation could degrade over time and lead to other potential problems.
Another property that this polyimide film demonstrates is that it is extremely hard wearing. This will mean that there will be less necessity to constantly replace these items, and in turn this will lead to cost savings. So it really does make sense for industries to make even more use of this material.
