Tape AL-25BT Aluminum Foil with Conductive Acrylic Adhesive Data Sheet Product Description 3M Tape AL-25BT consists of a soft aluminum foil backing and a unique electrically conductive, pressure-sensitive acrylic adhesive. • Soft aluminum foil backing • Conductive acrylic adhesive • Supplied on a removable liner for easy handling and die cutting • UL recognized for flame retardancy per UL 510, Product category OANZ2, File Please consult with a 3M sales representative about custom width and length. Standard length is 20M. 3M Tape AL-25BT is typically used for applications requiring excellent electrical conductivity from the application substrate through the adhesive to the foil backing. Common uses include grounding and EMI shielding in equipment, components, shielded rooms, etc. Shielding Effectiveness Shielding effectiveness depends on conductivity, permeability, thickness of metalization, adhesive strength, degree of contact, smoothness of application surface, strength and frequency of EMI signal, etc. However, using standard tests and fixtures, it is possible to determine a value for the attenuation.
