3M 1350 .5" x 72 yds Black Electrical Tape 2.5 mil

Electrical insulation tape

3M 1350 black electrical tape is a polyester film product with an acrylic adhesive system. It is supplied as a continuous single-sided roll measuring .5 inches wide by 72 yards long. The tape has a nominal thickness of 2.5 mil and is designed for general-purpose insulating and wrapping tasks in electrical and industrial environments.

Build integration and coverage

The .5 inch width suits tight bundles and small-gauge conductors where wider tapes would be cumbersome. A single roll provides 216 feet of material, allowing multiple splices or harness wraps without frequent roll changes. The polyester backing conforms to irregular shapes and resists abrasion during pull-through, while the acrylic adhesive bonds cleanly to wire jackets and terminal insulation.

Thermal and electrical limits

The tape carries a maximum performance temperature rating of 265 degrees Fahrenheit, defining its upper thermal limit in normal operation. No minimum temperature rating or voltage rating is specified by the manufacturer, so the product should not be relied upon for high-voltage insulation or extreme cold environments without separate validation.
