3M 7100061140 Polyimide Film Tape 2 Mil 500F Amber

Product Description

The 3M 7100061140 is a polyimide film tape designed for high-temperature masking, insulation, and hold-down applications in demanding electrical and industrial environments. The tape features a silicone adhesive backing bonded to an amber polyimide film carrier at 2 mil total thickness. It handles continuous operating temperatures up to 500 degrees F, making it suitable for wave soldering, conformal coating masking, transformer insulation, and motor winding work. Each roll measures 36 yards in length. Licensed electricians, motor rewinders, and electronics technicians are the primary installers and users of this product.

This tape is used across residential, commercial, and industrial applications wherever a thin, heat-resistant, electrically insulating tape is required. Common scenarios include masking circuit boards during reflow or wave soldering, insulating coil windings in transformers and motors, and securing components in high-heat environments. The amber polyimide film provides good visibility against most substrates, helping confirm coverage and placement before thermal processes begin.

Key Features

• Withstands continuous operating temperatures up to 500 degrees F (260 degrees C)
• Silicone adhesive provides reliable bond in high-heat environments without adhesive transfer
• 2 mil total thickness keeps profile low for tight clearance applications
• Amber polyimide film carrier offers good visibility during masking and inspection
• 36-yard roll length reduces changeover frequency in production environments

Compatibility

Designed as an OEM-style replacement and general-purpose polyimide film tape for high-temperature electrical insulation and masking applications across industrial, electronics, and trade service environments.

Installation Notes

This tape is typically applied by electricians, electronics technicians, and motor rewinding professionals. Surfaces should be clean and free of oils or contaminants before tape application to ensure proper adhesion. Power down and de-energize any electrical equipment before taping live conductor areas or winding assemblies. Follow applicable NEC guidelines and manufacturer procedures when using this tape as an insulating layer in electrical assemblies.
