3M 1181 Copper Foil Tape with Conductive Adhesive

3M™ Copper Foil Tape w/Conductive Adhesive 1181 is an electrically conductive, flame retardant, 2.6 mil metal foil tape used for EMI shielding and cable wrap applications. Featuring a deadsoft 1-ounce copper foil backing, this tape provides excellent solderability and resistance to oxidation and discoloration.

Dead soft 1-ounce (1.4-mil) copper foil backing for good shielding effectiveness and soldering
Conductive particles in the adhesive provides low contact resistance between the substrate and the backing to drain static charge
Flame Retardant per UL-510A Standard

Color: Copper

Liner Material: Clay Coated Kraft Paper

Backing/Carrier Material: Copper Foil

Adhesive Type: Electrically Conductive Acrylic

TotalThickness: 2.6 mil
