Insulating Polyimide Tape

This 3M 1205 amber tape uses a polyimide film with acrylic adhesive for high-temperature electrical insulation. Supplied as a continuous single-sided roll measuring 1/4 inch wide by 108 feet long, it operates reliably between minus 40 and 311 degrees Fahrenheit. The construction suits demanding masking and splicing tasks where thermal stability is critical.

High-Temperature Electrical Masking

Engineers and technicians performing wave soldering, coil wrapping or circuit-board masking will value the 3-mil film that withstands 311 degrees Fahrenheit without residue. Buyers needing a voltage-rated insulation product or a wider roll for cable harnessing should look at alternative specifications. The tape carries no voltage rating, so it does not meet dielectric-strength requirements for live-line work.

3-Mil Polyimide Film Thickness

The 3-mil thickness determines both conformability and heat resistance for precision masking jobs. Thinner films may tear during automated dispensing, while heavier films reduce flexibility around tight component leads. Confirm that 3 mils matches your process window before ordering.

Questions about this item

Will the 1/4 in width of the 1205 tape fit the narrow guides on my older taping machine?

The roll is 1/4 inch wide and 108 feet long, so it matches any guide or dispenser that accepts a quarter-inch tape.

How can I confirm the 1205 tape is holding at the 311 °F upper limit during a reflow cycle?

The polyimide film stays intact and the acrylic adhesive remains bonded up to 311 °F; inspect for discolouration or edge lift after the cycle to verify performance.

Does the 36-yard roll of 1205 come with a core or dispenser, or must I supply my own?

The product is a continuous 36-yard roll of 3-mil amber polyimide tape on a core; no dispenser or extra accessories are included.
