3M™ Thermally Conductive Interface Tape 8926 Series
Product Description
3M™ Thermally Conductive Interface Tape 8926 Series has 0.20mm, 0.25mm, and 0.50mm thick pressure
sensitive adhesive tapes filled with thermally conductive ceramic particles. These products are designed to
have good converting ability, handing and re-workability through the introduction of a thin PET carrier. 3M
tape series 8926 is designed with a soft acrylic polymer and multiple thickness options to allow excellent
wet-out or conformability to many surfaces. The tape series has good adhesion performance to many
substrate types and has excellent dielectric performance.
Product Uses
These products can be used for heat management in electronic devices and for general heat dissipation in
devices. They may also be used for bonding/joining parts in electronic products.
Key Features
• Good thermal conductivity (>1.5W/m-K)
• Excellent dielectric performance
• Low thermal impedance
• Good and reliable adhesion performance to Al and SS
• Vibration damping

* Thermal Conductivity Interface Tape 8926 Test Methods:
1.5W/m-K in XY direction per Hot wire plane Test method (Test equipment: QTM-500)
1.5W/m-K in Z direction tested in accordance with a simplified ASTM D5470 type method (Test equipment: T3ster DynTIM)
**Flame rating is only valid for the material coated on one side of aluminum plate with minimum 1.0mm thickness and the other side
of recognized component (QMTS2) FR-4 laminate at minimum 0.8mm thickness.
***Note: The end use customer application, design and verification testing will determine the final in use effective temperature range
based on each application’s environmental conditions.
Application Techniques
Bond strength is dependent upon the amount of adhesive to surface contact developed. Firm application
pressure helps to develop better adhesive contact and improve bonding strength
To obtain optimal adhesion, the bonding surfaces must be clean, dry and well unified. Typical surface cleaning
solvents are isopropyl alcohol and water (rubbing alcohol) or heptane. Note: Be sure to follow manufacturer’s
safety precautions and directions for use when using solvents.
Ideal tape application temperature range is 21°C to 38°C (70°F to 100°F). Initial tape application to surfaces at
temperatures below 10°C (50°F) is not recommended because the adhesive becomes too firm to adhere readily.
However, once properly applied, low temperature holding is generally satisfactory.
Storage and Shelf Life
The shelf life of 3M™ Thermally Conductive Interface Tape 8926 Series is 12 months from the date of manufacture
when stored in original cartons at 21°C (70°F) and 50% relative humidity.
