Polyimide adhesive tape is one of the most popular types of tape in use today. Its high chemical and temperature resistance and high insulation properties make it indispensable in many industries. In addition, it leaves clean surfaces after removal. As with all tapes, there are several types. These include single-sided tapes, double-sided tapes, and anti-static tapes.
Polyimide tapes are made up of an amber-colored polyimide film coated with silicone adhesive. They are ideal for high-temperature masking, circuit board gold finger protection, and 3D printing. They also offer exceptional tear resistance even at elevated temperatures. The tapes are available in various diameters and lengths, depending on their application. Custom sizes are also available if required.
Polyimide adhesive tape is self-extinguishing, which means that if a fire occurs, it quickly extinguishes, making it safer to use than other adhesive tapes. Its thickness is less than 0.05mm without liner, and it's 200kPa with a 6.5 kV dielectric strength. It also has excellent insulation properties.
Polyimide adhesive tape has a vapor pressure that is much lower than that of epoxy. Bubbles, however, can still be present in polyimide adhesive tape. Bubbles are caused by the presence of water molecules in the polymer. If this moisture is allowed to accumulate in the bubbles, it can cause cracks in the mold compound, reducing its reliability. Fortunately, polyimide adhesive tapes have several methods for reducing bubbles.
Polyimide adhesive tapes are available in a variety of thicknesses. The most common is 2-mil polyimide. This material is best for high-temperature applications. It also provides excellent puncture and electrical resistance. It can also be used in high-temperature masking and splicing applications.
Polyimide adhesive tapes are an essential tool for electricians. They are a thin, conformable polyimide film with exceptional adhesion and a very reasonable price. They are also used for a variety of applications, including insulating electric coils and 3D printer beds. It is also known by various names, such as adhesive Kapton.
Kapton tape is a trademarked form of polyimide tape. This tape provides high electrical insulation, low outgassing, and excellent electrical resistance. The tapes are available in different thicknesses and have a high-temperature resistance. The material is also resistant to chemicals. It can also be performed and metalized.
