Specialty Foil Tapes
Select a 3M specialty metal tape for applications such as:
• Lead foil tape for acid-resistant masking
during electroplating and anodizing;
radiopacity for x-ray markers
• Copper foil tape with or without conductive
adhesive for EMI/RFI shielding
• Stainless steel tape for sealing and
protecting of stainless steel surfaces
Electrical current

• Glass cloth-reinforced aluminum foil tape
for bundling wire harnesses

Tear-resistant 3M
™
Reinforced Aluminum Foil Tape
363 bundles wire harnesses and helps protect
wires, cables, and other flexible parts from heat.
Electrical current density is uniform across the
part because of the electrically conductive lead
foil. Both substrate and foil are plated, resulting
in a uniform plating thickness right up to the
plating stop-off line.
Uniform plating thickness with lead foil tape
Plastic tape
Metal
substrate
Electrical current density is intensified at the
plating stop-off line due to the non-conductive
properties of a plastic tape. The resulting plating
build-up necessitates an additional grinding
operation.
