3M 1182 Tape is a tape with a 1-ounce deadsoft copper foil backing that is coated on both sides with a unique electrically conductive pressure-sensitive acrylic adhesive. It offers good conductivity and ease of use.
3M 1182 Tape is a double‑sided copper foil product with a dead‑soft 1‑ounce copper backing and a conductive acrylic adhesive on both sides. It is supplied with removable liners for easy handling and can be ordered in standard or custom widths (¼" to 23") and lengths (standard 18 yards, longer on request). The tape is commonly used to bond conductive surfaces together for EMI shielding applications.
Key performance values include a backing thickness of 1.4 mil (0.04 mm), total thickness of 3.5 mil (0.088 mm), breaking strength of 25 Ib./in (44 N/10 mm), adhesion to steel of 35 oz/in (3.8 N/10 mm), electrical resistance through the adhesive of 0.010 Ω, and a flame‑retardancy rating of Pass per UL 510.
| Backing thickness | 1.4 mil (0.04 mm) |
|---|---|
| Total thickness (backing + adhesive) | 3.5 mil (0.088 mm) |
| Breaking strength | 25 Ib./in (44 N/10 mm) |
| Adhesion to steel | 35 oz/in (3.8 N/10 mm) |
