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 popular field that it can be found in is that of electronics, a couple of these properties do make it ideal for this purpose. One simple item really shows how it can utilized, this is the flexible flat cable which links the body of a laptop with the screen. This flexibility is a necessity when you consider who often a laptop gets opened and closed during a day.
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.
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.
Most materials and compounds would be affected by excessive temperatures. Some would shrink while others would stretch. Any form of distortion or damage will lead to the item no longer being able to fulfill the role for which it was originally intended. This sheet with its resistance to heat will suffer no such damage. The only change that a person might notice would be a slight darkening over a period of time.
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.
A prime example of something which operates at high temperatures could be something like an engine. They could be from a family car, an airplane, even a rocket used to put a satellite into orbit. This film does not conduct heat through itself so it is ideal if you need to protect something like engine cables. These previously unprotected cables often used to fail due to heat damage.
One more advantageous property that this polyimide film has is that it is very robust. As previously mentioned this can prevent damage to other items, the benefit of this is that the repair costs can be kept to the minimum. It is not surprising that industries are forever looking for more ways in which to use it.
