3M™ Aluminum Foil Tape 1115B has a 4.5-mil smooth aluminum foil backing with a conductive acrylic pressure sensitive adhesive and liner. The 4.5-mil aluminum foil is thicker than the standard 2-mil aluminum foil.
The 1115B tape with 4.5-mil aluminum foil backing has better conductivity and shielding effectiveness than standard 2-mil thick aluminum backing. Highly conductive particles in the acrylic adhesive provide a multitude of electrical paths between the application substrate and the surface of the copper foil. The acrylic adhesive has good resistance to heat, oxidation, solvents and oils. This tape is designed for a variety of applications: point-to-point electrical contact, thermal heat transfer, EMI/RFI shielding, grounding and static charge draining. These tapes can used in both electronic & electrical devices and EMI test laboratories for prototyping, design and troubleshooting. The 1115B tape is available from 3M in log rolls (standard size of 38.5 inch x 60 yds or 978 mm x 54,9 m) to 3M slitter/converters. Also, 3M offers to 3M authorized distributors (and 3M slitter/converters) various size slit rolls for resale to end users. Custom die-cut and formed parts are available from 3M slitter/converters.
