3M 1318-2 Yellow Electrical Tape

This 3M electrical tape uses abrasion-resistant polyester film with an acrylic adhesive. It comes in a continuous single-sided roll measuring .75 inches wide by 72 yards long. The tape has a 2 mil thickness and a maximum performance temperature of 265 degrees Fahrenheit. It carries no voltage rating.

Suits wire marking and bundling tasks

This tape suits electricians and technicians needing durable identification or bundling for wires and harnesses. The yellow colour aids visual coding in panels or automotive looms. Buyers who need a voltage-rated insulating tape for live conductor wrapping should look at a different product. It is also not for applications exceeding the stated temperature limit.

265 degree Fahrenheit temperature rating

The maximum continuous performance temperature of 265 degrees Fahrenheit is the key specification determining suitability. This limit defines the environments where the acrylic adhesive and polyester backing remain reliable. Always verify that the operating conditions stay within this threshold before specifying the tape.

Questions about this item

How does the 2 mil tape handle heat when a harness runs near a 265 °F component all day?

The polyester film with acrylic adhesive is rated for continuous exposure up to 265 °F, so it remains stable and does not degrade when installed next to high-temperature parts.

What tools or surfaces do I need before applying the 1318-2 tape to a wire bundle?

Clean the wire insulation so it is free of oil and dust, then wrap the tape by hand; no heat gun, activator or special applicator is required for the pressure-sensitive acrylic adhesive to bond.

Will the .75 in wide roll work on the thinner gauge wires I already have in the loom?

Yes, the three-quarter inch width conforms easily to small-diameter conductors and the flexible polyester film follows tight bends without lifting at the edges.
