3M 7100061139 Polyimide Film Tape 2in 108ft 1mil

Product Description

The 3M 7100061139 is a polyimide film tape with a silicone adhesive backing, designed for high-temperature masking, insulation, and protection applications in industrial and electrical service environments. The tape measures 2 inches wide and 108 feet long with a 1 mil total thickness, making it well suited for precise, low-profile wrapping around components. Its amber polyimide film construction maintains dimensional stability and dielectric integrity at continuous operating temperatures up to 500 degrees F (260 degrees C). Electricians, electronics technicians, and HVAC service professionals use this tape where conventional pressure-sensitive tapes would fail from heat exposure.

This tape is commonly used in electrical insulation, transformer winding, coil wrapping, printed circuit board masking during wave soldering, and high-heat wire bundling. It performs reliably in both residential and commercial applications where sustained elevated temperatures are present. The silicone adhesive bonds cleanly to most substrates and releases without leaving significant residue, which is important in precision electronic and electromechanical assembly work. It is also used in HVAC applications for sealing and insulating components near heat exchangers and burner assemblies.

Key Features

• Rated for continuous service up to 500 degrees F (260 degrees C)
• 1 mil thick polyimide film provides a low-profile, conformable wrap
• Silicone adhesive offers clean removal without heavy residue on most surfaces
• Amber film allows visual confirmation of underlying component markings
• 2 inches wide and 108 feet long per roll for extended coverage

Compatibility

Designed as an OEM-style general-purpose polyimide film tape suitable for electrical insulation, high-temperature masking, and coil or wire wrapping applications across industrial, commercial, and residential service environments.

Installation Notes

Installation is typically performed by licensed electricians or electronics technicians working on energized or thermally active components. De-energize and allow components to cool before applying tape in areas adjacent to live circuits or heat sources. Ensure surfaces are clean and dry before application to achieve full adhesive contact. Follow applicable NEC guidelines when using tape as supplemental electrical insulation.
