3M 7100037321 Thermally Conductive Tape 1 in X 36 Yd 2.0 Mil

Product Description

The 3M 7100037321 is a thermally conductive adhesive transfer tape designed for applications that require efficient heat transfer between bonded surfaces. The tape consists of a 2.0 mil thermally conductive adhesive layer carried on a 2.0 mil polyester liner. It ships in a 1-inch wide by 36-yard roll format, making it practical for production runs and field service work. HVAC technicians, electronics assemblers, and thermal management specialists use this tape when a thin, conformable bond line is needed to move heat away from a component or into a substrate without adding bulk or mechanical fasteners.

This tape is suited for mounting flexible heating foils, attaching temperature indicating films, and securing thermoelectric cooling modules to heat sinks. It also serves as a bonding layer for flexible circuits that need direct thermal contact with a heat sink. Applications span residential and commercial HVAC systems, refrigeration controls, and electronics assemblies where low-profile thermal bonding is required. The roll format allows the installer to cut to length on site.

Key Features

• 2.0 mil thermally conductive adhesive transfer construction for thin, conformal bond lines
• Carried on a 2.0 mil polyester liner for clean, controlled application
• 1-inch wide by 36-yard roll — cut to length as needed
• Suitable for mounting flexible heating foils and temperature indicating films
• Bonds flexible circuits directly to heat sinks for efficient heat dissipation
• Compatible with thermoelectric cooling module installations

Compatibility

Designed for use in thermal management assemblies involving flexible heating foils, temperature indicating films, thermoelectric cooling modules, and flexible circuits bonded to heat sinks.

Installation Notes

Surface preparation is critical for adhesive transfer tapes — clean bonding surfaces of oil, dust, and loose particulate before application. Apply firm, even pressure across the tape after placement to ensure full contact and proper adhesion. When integrating this tape into electrical or HVAC assemblies, de-energize the system before service in accordance with applicable NFPA 70 (NEC) or equipment manufacturer lockout procedures. Avoid stretching the tape during application, as distortion can compromise bond uniformity and thermal performance.
