POLYIMIDE TAPE DETAILS
Manufacturers create polyimide high temperature tapes by coating polyimide film with a desired adhesive system. The film thickness ranges from 0.5 mils to 10 mils, while the adhesive thickness ranges from 0.5 mils to 2 mils.
CGS coats both silicone and acrylic adhesives, ensuring clean removal without residue in high-temperature applications. Additionally, we have developed specialty adhesive systems that are low outgassing, ultra-thin, high temperature, and high tack. Polyimide tape is naturally amber, but we can supply it in other colours like green, red, or clear for easier colour coding
Max temp
Use standard polyimide film tape with silicone adhesive in applications up to 260°C (500°F). For higher temperature resistance, choose our HT version, which uses a special grade of silicone adhesive, allowing the tape to withstand up to 300°C (572°F).
Shelf life
Polyimide with pressure-sensitive adhesive (PSA) has a shelf life of 2 years from the date of manufacture when stored at 75°F and 50% relative humidity.

APPLICATIONS
Their properties make them an excellent choice for any high temperature and electrical insulation applications, such as coil insulation, magnetic wire insulation, automotive/aerospace electronics, high temperature powder coating masking and masking of printed circuit boards in the wave soldering process.
ELECTRICAL INSULATION
Polyimide tapes are excellent for high temperature and electrical insulation applications. Use them for magnetic wire insulation and automotive and aerospace electronics.
Aerospace
Insulate wiring on satellites, spacecraft, and launch vehicles with polyimide tape due to its thermal insulation and radiation resistance properties. Use it as wire and cable insulation on aircraft because of its high mechanical strength, dielectric, and thermal insulation properties.
High Temperature Masking
Use polyimide tape for high temperature applications up to 560°F (300°C). Its amber color ensures easy identification and alignment. Its high dimensional and exceptional tensile strength allow it to break through cured paint without silvering or tearing. Common uses include masking parts for powder coating, masking edges of overlap seams, e-coating, electroplating, anodizing, and separating dissimilar metals. It resists shrinking, curling, and edge lifting, and removes with zero adhesive residue.
