Amber Polyimide Electrical Tape

This 3M 1218 series tape uses a polyimide film backing with an acrylic adhesive system. The amber colour identifies the high-temperature formulation designed for electrical insulation tasks. Supplied as a continuous single-sided roll measuring 36 yards in length by one-half inch wide. Suitable for professionals requiring reliable dielectric protection.

356 °F maximum performance temperature

The tape maintains its electrical and mechanical integrity up to 356 degrees Fahrenheit, making it the decisive specification for high-heat environments. It carries a 600-volt rating for standard low-voltage insulation work. Buyers needing performance above this temperature threshold should evaluate alternative materials.

Single roll, no dispenser included

The package contains one 36-yard roll without a built-in cutter or dispenser accessory. Users must provide their own cutting tool or tape gun for application. No additional software, liners, or mounting hardware are supplied with this product.

Questions about this item

How does the 356 °F maximum performance temperature affect real-world use?

The tape maintains adhesion and insulation up to 356 °F, so it stays reliable in high-heat electrical environments such as motor leads or transformer connections.

What does the 600 V voltage rating cap in practice?

The 600 V rating means the tape is certified for insulating splices and terminations on circuits up to 600 volts; it should not be used on higher-voltage systems.

Will the 1/2 in width by 36 yd roll fit a standard dispenser?

The 1/2 inch width matches common handheld tape dispensers, and the 36 yard length provides enough material for multiple jobs without frequent roll changes.
