Important Information Regarding Polyimide Film

By Jeanette Riggs


Polyimide is a product that has been used for a large number of applications since it came into production in the 1950's. The product is known as PI, and it has extremely durable and resistant properties. It is also not very heavy, which is beneficial in many circumstances, and even chemicals cannot destroy its form. For this reason, it is a very good material from which to make insulation tape, and polyimide film is used in many industries today.

Its durable nature is very resistant to chemical substances. Most known substances cause this type of tape no harm, and do not erode it or weaken its structure in any way. There is virtually no way to dissolve it. This means that it can be used for many purposes. High and low temperatures have no effect on the tape either, and it is therefore often used in extremely hot or cold environments. It can even withstand cold of minus two hundred degrees Celsius.

Similarly, the tapes can be used in applications where heat of 400 degrees Celsius is recorded. They do not melt or break down in any way. Moisture is not a problem either, as the tapes are not effected by the presence of water. This property ensures that they form an effective moisture barrier for the parts that they are used to protect.

One will most often find these sorts of films covering electrical wires or other electronic components. They are excellent insulators for magnetic wiring, capacitors and transformers, and are also used over all other types of wires and cables. A large number of industries therefore find the tape to be extremely useful.

This kind of tape has literally been to the moon and back, as it is used for the wiring in spacecraft. The scientists who developed this kind of air travel quickly found that it was the best material to use within their constructions. This is because the tape is so durable. It is also used in the airplanes that travel around the world.

In the automotive industry, the tapes are used for safety and convenience. Parts of a motor vehicle are often subjected to high temperatures, and are also often moving parts. Since that the tape is so flexible, it is ideal for moving parts that are under high pressure. Regardless which way it is twisted, it will not crack or tear. In general, it is used in numerous applications that enhance the safety of workers within an industry, and the safety of consumers who purchase products.

Films can be purchased offline and online, and in a wide range of lengths and thicknesses. A customer must decide upon the right sort of tape to purchase depending on the type of duty it needs to perform. A customer could also have tape made according to specific measurements.

Most types of polyimide film have a smooth and shiny surface, and are packed in boxes that state their nature. Information such as the date of their manufacture is useful, as it is of optimum quality within two years of this date. The package should state its measurements as well and its place of manufacture.
