There are few people who have heard of polyimide film. There are even fewer who can say how it gets utilized, even though its use is so wide spread today. Modern industries have been quick to make use of the useful properties that are associated with this material. Whilst being lightweight its also very flexible and strong, with good resistivity towards chemicals and heat.
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.
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.
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.
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.
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.
