3M™ 1181 Tape consists of a 1-ounce deadsoft copper foil backing and a unique electrically conductive pressure-sensitive acrylic adhesive.

• Copper foil with conductive acrylic adhesive
• Deadsoft 1-ounce copper foil backing
• Supplied on a removable liner for easy handling and diecutting
• The copper foil backing is solderable and resists oxidation and discoloration
• Common uses include grounding and EMI shielding in equipment, components, shielded rooms, etc.

• Extreme Hot and cold temperature versatility. 3M foil tape works in temperatures to which other tapes would diminish. Performing in cold conditions allows this 3M tape to be a market leader, as other tapes see the adhesive harden and begin to lose sticking strength. On the contrary, extreme heat can melt adhesives of tapes, but not the 3M foil tape making it versatile for most applications.

• An Acrylic Adhesive backing. This 3M Aluminium foil tape is coated in a superior acrylic adhesive, which works well in extreme cold and heat conditions. This matters when comparing to most duct tapes that are made with a rubber adhesive. This is then known to delaminate from its backing in these extreme conditions. Other adhesives can offer greater resistance but will lack mechanical strength, poor ageing resistance and UV light.

• Longevity of foil tape. Within the construction industry, the use of pressure sensitive tapes is often used in hard to reach areas. This means they can't be easily replaced or repaired. The acrylic adhesive on the 3M aluminium foil tape offers better cohesion, adhesion and thermal properties.

Need to shield electrical components from electromagnetic interference? This conductive smooth copper tape from 3M will do the job efficiently. It features a unique electrically conductive pressure-sensitive acrylic adhesive that provides an adhesion strength of 3.8N/cm, so it holds firmly in place once applied. Thanks to an operating temperature range of -40°C to +130°C, you can rely on it to perform in extreme conditions where other tapes would come unstuck.

• Copper foil backing is solderable so you can make secure connections• Supplied on a removable liner to make it easy to handle and die-cut• Tensile strength of 44N/cm makes it a robust choice• UV resistance provides increased longevity• Copper resists oxidation and discolouration

• Electromagnetic or radio-electrical shielding• Grounding and EMI (electromagnetic interference) shielding in equipment

This conductive copper tape is conductive on both sides, meaning you can join multiple lengths to make an electrical connection. However, this type of electrical connection can weaken over time, so a single strip of copper tape is a better conductor than several lengths joined together.
