3M™ 4008 Double Sided Foam Tape is a 1/2-inch wide, 36-yard roll built around a 1/8" open cell polyurethane foam carrier coated on both sides with a firm acrylic adhesive. The conformable foam core fills gaps on irregular or uneven surfaces, distributes stress across bonded areas, cushions against impact, and dampens vibration for durable, load-bearing bonds.

This tape is well suited for bonding, mounting, and sealing tasks in manufacturing, fabrication, and industrial assembly environments. Its acrylic adhesive system resists elevated temperatures and solvents, making it a reliable choice for applications where bond integrity must hold under thermal cycling or chemical exposure — indoors or in protected exterior installations.

The foam carrier's high shear strength supports demanding structural bonds on a variety of substrates. The 1/2" width is compatible with standard narrow-foam tape dispensers, and the tape is sold as a single roll per pack for straightforward quantity management.
