3M Electrical Tape: 1/2 in Wd, 36 yd Lg, 3 mil Thick, Polyimide Film, Acrylic

3M 1218 high-temperature electrical tape is used for insulating electrical components, coils, capacitors, and transformers in applications requiring thin, heat-resistant polyimide film. It withstands up to 600 V and is common in electronics, motor repair, and aerospace industries where acrylic adhesive and 3 mil thickness provide reliable dielectric strength.

3M 1218 tape is 1/2 inch wide, 36 yards long, and 3 mils thick. It is made of polyimide film with acrylic adhesive, rated for 600 V. The series is 1218, and the manufacturer part number is 1218. This tape is designed for high-temperature electrical insulation in demanding industrial environments.

3G Electric supplies 3M 1218 electrical tape worldwide. We interpret your demand, source the OEM-specified tape, and handle full logistics, customs, and delivery to your facility. Contact us for availability and lead time. We deliver across 14 industrial departments, with specialist depth in controls to support your insulation needs.

Clean the surface thoroughly to remove oils and debris. Apply 3M 1218 tape with light tension, overlapping 50% for insulation layers. Avoid stretching the polyimide film. For best adhesion, apply at temperatures above 50 °F. This acrylic adhesive bonds well to most substrates used in electrical insulation.
