General Information:
Polyimide tape consists of Polyimide film and adhesive system that make it the ultimate in high temperature tapes. It is also known as Kapton® tape and has the ability to maintain its excellent physical, mechanical, and electrical properties over a wide temperature range and performs as well as any product at high temperatures. Polyimide tape has an excellent dielectric strength and remove cleanly leaving no residue.
Polyimide film is a kind of a high performance polymer through polycondesation of symbenzene tetracarbonic acid dianhydride and diaminodiphenyl ether, which combines excellent physical, electrical, and mechanical properties at temperatures as low as -452°F (-269°C) and as high as +752°F (+400°C). PI film offers excellent dimensional stability combined with excellent chemical resistance.
Applications:
Because of these properties, Polyimide tape is used in various applications in electronic, automotive and general manufacturing industries. This tape can either be amber or clear in color, and the film thickness ranges between 1 and 5 mils while the adhesive may range from 1 to 2 mils thick. It may be double sided, and the adhesive may be silicone or acrylic based. Anti Static kapton tape is used in circuit board construction and can be used in electrical applications where static is an issue.
Some of Polyimide tape’s primary uses are in electrical applications such as coil insulation, capacitor and transformer wrapping or insulation, magnetic wire insulation, and in gold leaf masking during wave soldering. It is also used as a very high temperature mask during powder coating applications.
Polyimide tape is also used in the auto industry for wrapping switches, diaphragms, sensors and coils in seat heaters. The aerospace industry uses it primarily for insulation of aircraft and spacecraft wings. It's unique ability to maintain its physical, mechanical and electrical properties and its wide temperature range makes it appealing to a wide range of industries applications. Finally, Polyimide tape can be laminated, metallized and punch formed; and these capabilities make it a candidate for converting to custom shapes and sizes.
