1. Product Overview

3M™ Double Coated Urethane Foam Tape 4008 is an off-white, 3.2 mm (0.125 in) thick, open-cell, flexible urethane foam tape with double-sided high-temperature acrylic adhesive (3M™ Adhesive 100). The tape combines conformable foam with strong pressure-sensitive adhesion to fill gaps, bond irregular surfaces, and provide long-term holding strength up to 104 °C. Its durable foam construction dampens vibration, aids component cooling, and ensures reliable performance in interior mounting and industrial applications. A green densified kraft paper liner facilitates precise application while protecting the tape from humidity extremes.

2. Applications

  • Interior and protected exterior mounting of signs and nameplates

  • Mounting dispensers, air fresheners, and acoustic panels

  • Electronic assemblies requiring thicker foam for gap filling

  • General bonding, attaching, and mounting applications where vibration damping is required
