3Mâ¢ Aluminum Shielding Tape 1170 has a 2.0-mil smooth aluminum foil backing with a conductive acrylic pressure-sensitive adhesive and liner. Aluminum is an alternative conductive backing material to copper.
Application:-3M Aluminum Foil Tape 1170 is typically used as an EMI/RFI shielding tape for applications in the electronics industry such as static charge draining, seaming shielded rooms, cable wrapping and surface contact to non-solderable materials.
Shielding Effectiveness:-Many factors determine true shielding effectiveness of a shielding tape, including type and thickness of foil, adhesive type, intimacy of contact, smoothness of application surface, frequency of the EMI signal, etc. Typical shielding effectiveness for 1170 Tape is >85dB, 1MHz to 2 GHz, ASTMD-4935 test method.
