High-strength conductive aluminum foil tape with dead soft backing for EMI/RFI shielding, circuit repair, and electronics applications. Features aggressive acrylic adhesive, wide temperature range, and excellent conformability to irregular surfaces.
3M™ Conductive Aluminum Foil Tape 3302 is a high-strength, dead soft aluminum foil coated tape specifically designed for printed circuit manufacture and repair, shielding applications in the electronics industry, and low-level EMI and RFI shielding applications. This premium tape features a 2 mil aluminum foil backing that is durable and malleable, allowing it to conform to uneven or irregular surfaces with ease. The dead soft aluminum foil backing ensures flexibility while maintaining structural integrity for demanding industrial applications.
The tape is coated with an aggressive conductive acrylic adhesive system that bonds exceptionally well to a diverse selection of materials, including those with low surface energy and difficult textures. It features excellent "wetting out" capabilities to all textured surfaces, ensuring reliable adhesion in challenging environments. This thermally conductive tape is ideal for heating and cooling efficiency applications and helps reflect heat and light effectively. The tape resists flame, moisture, weather, UV degradation, and many chemicals, making it suitable for all-weather electronic shielding needs.
With a wide temperature range from -40°F/-40°C to 250°F/121°C, this UL510 listed tape can be used in a variety of low and high-temperature applications. Each case contains 2 rolls of 36-yard tape, with an overall width of 4 inches (101.6 mm) and total thickness of 3.5 mil. The glassine paper release liner helps preserve the adhesive prior to application and assists in proper tape placement. Perfect for aerospace, automotive, construction, electronics, and military applications requiring reliable EMI/RFI shielding.
