1318-1 Yellow Electrical Tape

3M 1318-1 is a yellow insulating tape built with a polyester film backing and an acrylic adhesive. It comes in a continuous single-sided roll measuring .25 inches wide and 72 yards long. The tape has a thickness of 1 mil and is designed for electrical and industrial wire applications. It is supplied in new condition.

Polyester film and acrylic adhesive

The polyester film backing provides abrasion resistance for durability during installation and use. Acrylic adhesive delivers reliable bonding across a range of surfaces. The tape operates up to a maximum performance temperature of 265 degrees Fahrenheit. No minimum performance temperature or voltage rating is specified by the manufacturer.

General electrical insulating tasks

This tape suits professionals and DIY users needing a thin, abrasion-resistant wrap for wire identification and insulation. Buyers who require a voltage-rated product or a tape certified for low-temperature environments should look at alternatives. The 1 mil thickness may not meet requirements for heavy-duty mechanical protection.

Questions about this item

Will the 1 mil polyester film backing on the 1318-1 tape need replacement after repeated abrasion?

The 1 mil polyester film backing is designed for abrasion resistance, reducing the need for frequent replacement during normal insulating use.

Does the 265 Degrees F maximum temperature limit appear before the acrylic adhesive fails under sustained load?

Yes, the 265 Degrees F maximum performance temperature is the primary thermal limit for the acrylic adhesive system.

Does the .25 inch wide roll generate noticeable heat during all-day electrical insulation work?

No, the tape is a passive insulating material with no power draw, so it produces no heat during continuous application.
