3M Scotch 1181 Copper Foil Shielding Tape, 16.5 m x 6 mm, Conductive Acrylic Adhesive, 1 Roll 11816

Electromagnetic interference (EMI) and radio frequency interference (RFI) can disrupt sensitive electronics, causing signal degradation and equipment malfunction. The 3M Scotch 1181 copper foil tape provides a reliable solution for shielding, grounding, and static discharge in electronic assemblies. Made from high-purity copper foil with an electrically conductive acrylic adhesive, it offers excellent conductivity through the adhesive thickness (Z-axis) for effective EMI/RFI shielding. The tape is 6 mm wide and 16.5 m long, with a total thickness of 0.066 mm, allowing it to conform to irregular surfaces while maintaining strong adhesion. It withstands temperatures from -40°C to 155°C and meets ASTM D 1000 standards, making it suitable for demanding electronic applications.

Who is it for

This tape is intended for electronics engineers, technicians, and manufacturers who need to shield components, create grounding paths, or repair circuits. It is ideal for use in prototyping, production, and maintenance of electronic devices, including computers, telecommunications equipment, and consumer electronics.
