Industrial-grade polyester tape for electrical work

3M 1318-2 is a yellow polyester film tape with an acrylic adhesive, supplied as a continuous 72-yard roll one inch wide. The two-mil backing resists abrasion and remains stable up to 265 degrees Fahrenheit. It is intended for general electrical insulation and wire harness wrapping in industrial and automotive environments.

Suits technicians who need thin.

The single-sided construction and continuous roll format work well for long harness runs and repetitive wrapping tasks. Installers who require a voltage-rated product or a tape rated for sub-zero flexibility should evaluate alternatives that carry those specific certifications.

Maximum operating temperature of 265 degrees

This upper limit defines the thermal envelope for the acrylic adhesive and polyester film. Verify that the application environment stays within this boundary before specifying the tape for high-heat zones.

Questions about this item

Is the 1318-2 tape sold in a single 72-yard roll or in multiple shorter rolls?

The product is supplied as one continuous roll measuring 72 yards in length.

What does the 265-degree Fahrenheit rating mean when the tape is used in a live circuit?

It indicates the highest continuous operating temperature the polyester film and acrylic adhesive can withstand without losing adhesion or mechanical strength.

Does the tape carry a voltage rating that limits the circuits it can insulate?

The specification lists the voltage rating as Not Rated, so the tape should not be relied upon as primary electrical insulation for any specific voltage class.
