3M™ Copper Foil Tape 1181 consists of a 1-ounce rolled copper foil backing and an electrically conductive, pressure-sensitive acrylic adhesive. This tape is supplied on a removable liner for easy handling and die-cutting. It has excellent solder ability.
FEATURES
- Dead soft 1-ounce (1.4-mil) copper foil backing for good shielding effectiveness, soldering and converting (slitting and die cutting).
- UL recognized flame-retardancy per UL 510 for applications needing this property.
- Conductive particles in the adhesive provides low contact resistance between the substrate and the backing to drain static charge.
- Acrylic pressure-sensitive adhesive has good resistance to heat, oxidation, solvents and oils.
- Removable liner makes it easy to handle and die cut complex shapes.
- There are both standard and custom roll widths and lengths to meet a variety of application needs.
APPLICATIONS
- EMI Shielding
- Grounding
- LV Conductor
