High-Temperature Polyimide Tape for Electrical

3M 1205 amber tape uses a polyimide film backing with acrylic adhesive for reliable electrical insulation. It suits technicians and engineers who need consistent performance during soldering, masking or coil wrapping tasks. The continuous roll format supports both manual and automated dispensing workflows.

Operating Range from -40 Degrees F to 311 Degrees F

The tape maintains adhesion and dielectric strength across a wide thermal window without melting or leaving residue. Acrylic adhesive resists solvent exposure and remains stable during reflow cycles. No voltage rating is assigned, so users must validate suitability for each specific circuit.

Single-Sided 36 yd Roll with 1 in Width

A continuous single-sided construction simplifies tear-off and reduces waste during repetitive applications. The amber colour allows visual inspection of underlying traces or components. Build quality reflects 3M manufacturing standards for cleanroom-compatible materials.

Questions about this item

How do I apply the 1 in wide 1205 polyimide tape without trapping air bubbles?

Clean the surface, then unroll the 36 yd tape slowly while pressing firmly with a roller or thumb from the centre outward to push air out before the acrylic adhesive sets.

When will the 1205 tape need replacement after repeated heat cycles?

Replace it once the amber polyimide film darkens, cracks or loses adhesion after exposure beyond the -40 °F to 311 °F performance range.

At what temperature does the 1205 tape start to degrade during continuous operation?

The acrylic adhesive and polyimide backing are rated to 311 °F; sustained use above that limit causes the tape to break down first.
