3M Conductive Copper Tape 50.8mm x 16.5m, 130°C Max, Acrylic Adhesive, 1181-50.8

The 3M 1181-50.8 Conductive Copper Tape is a high-performance solution designed for electromagnetic and radio-frequency shielding in demanding industrial environments. With a robust copper foil backing and an electrically conductive, pressure-sensitive acrylic adhesive, this tape provides reliable electrical conductivity from the substrate, through the adhesive, to the foil backing. Its unique construction ensures it is suitable for both electrical and mechanical stress applications.

This tape offers a substantial width of 50.8mm and a total length of 16.5m, catering to professional and large-scale installation requirements. It is manufactured using dead-soft copper, which not only enhances its electrical performance but also ensures flexibility for conforming securely to irregular surfaces. The tape can be easily die-cut and handled, thanks to the removable liner provided.

Designed to perform in extreme conditions, the 3M 1181-50.8 is resistant to humidity, mould, ultraviolet radiation, and solvents. Its operational temperature spans from -30°C to 130°C, making it ideal for environments subjected to fluctuating or high temperatures. With an adhesion strength of 3.8N/cm and a tensile strength of 44N/cm, it sustains integrity under mechanical stress, providing long-term durability in industrial settings.

The tape's double-sided conductivity enables it to be soldered and ensures that electrical connections are consistently reliable, even across multiple taped lengths. These features make it a preferred choice for grounding, EMI/RFI shielding in equipment and shielded rooms, and manufacturing contexts where precise and robust electromagnetic containment is critical.

Primary applications include shielding sensitive electronic equipment from external electromagnetic interference, establishing reliable ground paths within assemblies, and forming the conductive barriers required in the construction of shielded rooms.

The tape complies with rigorous industrial requirements and is suitable for manufacturing, laboratory, electronics assembly, and related sectors. It is not certified to EN standards but offers proven performance for general and advanced industrial use cases.

Package includes one roll of 3M 1181-50.8 Conductive Copper Tape, 50.8mm x 16.5m, supplied with a removable liner for easy application. For more options or to browse related industrial tapes and shielding solutions from 3M, explore the Metallic Tape category on EnvMart.
