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.
A couple of these properties make it an ideal material for use with modern electronics. A common example that illustrates this point is the flat flexible cable which connects the body of a laptop to the screen. It is easy to understand the need for flexibility as a laptop is opened and closed on such a regular basis.
Should you get the opportunity to see a dismantled laptop computer, the cable that has just been mentioned will be easy to identify. It will be of an amber color and the metal tracks will be clearly seen. The amber colored sheeting is this versatile material.
The metallic tracks will be firmly fixed to the sheet by an adhesive. Due to the insulating properties of the sheeting its even possible to have tracks running either side of the sheet, but further insulation will be required to prevent any possible shorting between the tracks and the case. Other uses in the electronics world also includes masking areas of circuit boards, also providing insulation to such devices as capacitors and transistors.
Possibly one of the most important factors that this material has is the heat resistance. As a consequence this material can often be used in areas which would be subjected to high temperatures. The material will withstand temperatures into the region of 800 degrees Fahrenheit.
Routinely any material which becomes affected by heat will either distort or degrade. It will either shrink or stretch. Either effect will cause the affected material to become unfit for the original purpose. Its therefore a real plus when you note that this material suffers virtually no obvious effects when subjected to the same treatment. In fact the only thing that people might notice will be a slight darkening.
When it was initially developed, this material was used almost exclusively by the military and by the defense industry. Since entering into the mainstream civilian industries the applications that it is now used in have really increased. These applications can range from micro electronics in medicine to space agencies.
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.
